Best MCP Servers for Marketing in 2026

Read from each vendor's MCP documentation and pricing page on October 28, 2026. Sources are linked in each entry below.

1. 1

   Spreadcast

   Free plan makes 3 posts to download. Pro is $29 a month with publishing to 10 social accounts

   Best for social publishing: designs the post in your brand, writes captions per network and publishes after you approve

   Spreadcast is marketing automation for social media, built first for App Store apps, and its MCP server lets Claude, ChatGPT, Claude Code, Cursor and other MCP clients run it from a chat. Ask for a post and the assistant designs the picture in your brand, with your colors, fonts, logo and a real screenshot of your app in an iPhone frame when your brand kit has one. Ask for a carousel and it designs the slides in one look. It then writes a caption for each network inside that network's limits, saves the post as a draft, and schedules or publishes it once you approve. Businesses without an app start from a website or a short description of the brand instead of an App Store link.

   The server also reads what Spreadcast found on your App Store listing. Spreadcast checks the listing every day, and when a new version goes live or the app reaches a ratings milestone, it turns that moment into a post. Through MCP the assistant can list those moments, design the moment post, skip the ones you do not want, read your brand kit and posting rules, and pull analytics: followers and interactions per network, and likes, comments, reach and views per post. So one conversation can go from what happened this week to a designed post on Instagram, Facebook, Threads, LinkedIn, Pinterest, TikTok, YouTube, Bluesky, Mastodon, Telegram and Discord.

   Safety is built in rather than bolted on. On the consent screen you choose whether a connection may only make drafts or may also publish. Approving a post is its own step, either in Spreadcast with one tap or through an approve tool when you granted publishing access, and the assistant is told to show you what will go out, where and when before it asks. Claude and ChatGPT connect with Sign in with Spreadcast at spreadcast.app/api/mcp, so there is no key to paste; Claude Code and Cursor can use an API key in a header. Every connection is listed in Settings and can be removed at once.

   Pricing on the pricing page: Free is $0 for one app and makes 3 posts to download with a small Spreadcast mark, without publishing. Pro is $29 a month or $290 a year for clean posts with no cap, publishing to 10 social accounts across any mix of networks, autopilot or one tap approval and posting from Claude or ChatGPT. Studio is $79 a month for 5 apps and 50 accounts, each with its own brand. If you would rather not subscribe, a Post Pack is $19 once for 10 posts designed and published. The full tool list is on the Spreadcast MCP server page.

   Pros

   • The only server here that publishes organic social posts
   • Designs posts and carousels in your brand, with real app screenshots
   • A caption per network, inside each network's limits
   • Drafts first, with approval as its own step
   • Turns App Store releases and rating milestones into posts
   • Sign in with Spreadcast in Claude and ChatGPT, no key to paste
   • Posts to Telegram, Threads, Bluesky and Mastodon as well as the big networks

   Cons

   • Built for app makers first, so the automatic moments come from an App Store listing
   • No ads, SEO or email tools: pair it with the servers below
   • Publishing needs Pro or a Post Pack
2. 2

   Meta Ads

   No fee stated on Meta's MCP pages. You pay for ad spend

   Best for paid social: create and manage Facebook and Instagram ads from chat, with new ads starting paused

   Meta runs its own Ads MCP server at mcp.facebook.com/ads. Meta's overview calls it a Meta hosted server for managing Meta ads from an AI agent and groups its tools into seven areas: reporting, ad creation and management, catalogs, signals and datasets, help and troubleshooting, A/B tests and conversion lift studies, and activity logs. It works with any MCP client, and Meta's Business Help Center article names ChatGPT, Claude, Claude Code and Perplexity as supported agents, all using the same address.

   The part that matters most is on Meta's ad creation and management page. Tools create campaigns, ad sets and ads in a paused state, and a separate activate tool switches them live, which starts spending budget. Meta says the AI client asks for confirmation before activation. The same page lists a tool that boosts an existing organic Instagram post, a search of the public Ad Library for competitor research, ad previews in Feed, Stories and Reels, and custom audience tools, including one that uploads hashed customer data and one that deletes an audience.

   Meta's get started page says owning a Meta app is not required. The usual route is OAuth: your client sends you to Facebook Login for Business, you sign in and approve the permissions, and no token setup is needed. Developers can also use a user access token or an employee role system user token. The minimum permissions are ads_mcp_management plus ads_read or ads_management, with catalog, business, Pages and Instagram permissions adding more tools. The page gives a one line Claude Code command and a ChatGPT developer mode setup. The best safety feature is in Meta Business Suite, not in the chat: under Settings, Integrations, Ads MCP server, someone with full control of the business portfolio can allow or block actions per ad account, such as creating campaigns or editing budgets, and can block any budget above an amount you set. Meta says the server enforces those rules. Meta's pages we read do not mention a price. For organic Facebook posting, see our Facebook MCP server guide.

   Pros

   • Official and hosted by Meta
   • Creates campaigns, ad sets and ads in a paused state
   • Boosts an existing Instagram post
   • Ad Library search for competitor creative
   • No Meta app needed for the OAuth route
   • Business Suite rules that block campaign creation or cap budgets

   Cons

   • Activating an ad spends real money, so read every confirmation
   • Audience tools can upload hashed customer data and delete audiences
   • Does not design the creative or publish organic posts
3. 3

   Google Analytics

   Free. Google Analytics and the server cost nothing

   Best free analytics server: ask GA4 questions in plain words, read only

   Google publishes the Google Analytics MCP server as open source in its googleanalytics GitHub organization, under the Apache 2.0 license. Google's developer page says it can answer questions about your data, such as user counts and top selling products, and help with data driven marketing plans, and that it is for read only requests and cannot change your Analytics settings.

   The repository's README lists the tools: account summaries, property details, linked Google Ads accounts, property annotations, standard reports, funnel reports, custom dimensions and metrics, and realtime reports. One write tool exists, creating a property annotation, and it only appears when you start the server with a write flag and grant the edit scope. Everything else runs on the read only Analytics scope. The README still labels the project experimental.

   Setup is the catch. It is a local Python server: you install pipx, enable the Analytics Admin and Data APIs in a Google Cloud project, create Application Default Credentials with the read only scope, and add the server to your client's config file. Google's page includes configuration for Antigravity and for Claude Desktop. If you have never touched Google Cloud, budget a quiet hour for the first setup rather than squeezing it between meetings. Google Analytics itself is free, and so is the server. If you mostly want to see how your social posts drive traffic, pair it with our campaign link generator so the sources are labeled before you ask.

   Pros

   • Official, open source and free
   • Read only by default, on the read only Analytics scope
   • Standard, funnel and realtime reports
   • Shows which Google Ads accounts link to a property

   Cons

   • Runs locally, with Google Cloud credentials to set up
   • No hosted address to paste into Claude or ChatGPT
   • Still labeled experimental in the README
4. 4

   Semrush

   MCP access listed from Starter at $199 a month, after a 7 day trial

   Best for SEO and competitor data inside Claude or ChatGPT, with a listed app in both

   Semrush runs a hosted MCP server at mcp.semrush.com/v2/mcp. Semrush's developer docs say it exposes every SEO API method, every Trends API method your subscription covers, and read only methods from the Projects API, so an assistant can pull project data but cannot create projects or change settings. Semrush's knowledge base puts it plainly: the connection is read only, and your assistant can retrieve Semrush data but cannot modify or delete it.

   Sign in is OAuth 2.1 by default, with an API key in a header as the fallback for clients without OAuth. The knowledge base says Semrush is an official app in ChatGPT, Claude and Perplexity, and the developer docs list Claude, Claude Code, ChatGPT, Cursor, VS Code, Microsoft Copilot, Perplexity, Lovable, Notion and Antigravity as supported clients.

   Every query spends API units. The developer docs say the standard API route includes 50,000 units that refresh on your renewal date, with packages of 2, 5, 10 or 20 million units on higher plans, and that a Trends API plan includes MCP access. On Semrush's pricing page the Starter plan, $199 a month billed monthly or $165.17 billed yearly, lists MCP access; Pro+ is $299. The knowledge base's tip is worth following: ask for the top 50 keywords in one country, not all keywords everywhere, because an open ended question can spend far more units than you expect.

   Pros

   • Hosted, with OAuth and a listed app in Claude and ChatGPT
   • SEO, Trends and Projects data in one server
   • Read only, so nothing in your account changes
   • Long list of supported clients

   Cons

   • $199 a month before you get MCP access
   • Every question spends API units
   • Traffic and market data need a Trends plan
5. 5

   HubSpot

   Free. The connector is included on every HubSpot tier

   Best CRM server: read and write contacts, deals and tasks, free on every tier

   HubSpot's remote MCP server at mcp.hubspot.com became generally available on April 13, 2026, per HubSpot's changelog. It reads and writes CRM records (contacts, companies, deals, tickets, line items and products) and activities such as calls, meetings, notes, tasks and emails, so an assistant can log a call, create a follow up task or draft an email. Marketing content, which covers campaigns, landing pages, blog posts, site pages and marketing events, is read only.

   HubSpot's MCP page says access is controlled through a user level app and its scopes, that an admin connects first, and that custom sensitive data properties stay out of reach. Connections use OAuth 2.1 with PKCE. The remote server docs say HubSpot also offers ready connectors for Claude, ChatGPT, Microsoft Copilot and Gemini, built on the same server. HubSpot runs a second, separate Developer MCP server for people building apps with its CLI; marketers want the remote one.

   HubSpot's Claude page says it is an official connector built by HubSpot, that it is free, and that all tiers get features such as leads, landing page creation, content analytics and conversations. HubSpot's pricing starts Marketing Hub at $0 for up to 2 users. For a small team that already keeps leads in HubSpot, this is the cheapest useful marketing server on the list.

   Pros

   • Free on every tier, including the free CRM
   • Reads and writes records, tasks, notes and emails
   • Ready connectors in Claude, ChatGPT, Copilot and Gemini
   • Your HubSpot permissions still apply

   Cons

   • Campaigns, landing pages and blog posts are read only
   • An admin has to connect before the rest of the team
   • Writes to your CRM, so keep approval prompts on
6. 6

   Canva

   Works on a free Canva account. Some tools need Canva Pro, Business or Enterprise

   Best design server: make and edit Canva designs from chat

   Canva's MCP server powers the Canva AI Connector. Canva's developer docs list what it lets an assistant do: create designs from a text description, edit existing designs in plain words, search your designs and folders, upload and organize assets, use brand kits and templates, export to PDF, PNG, JPG, PPTX or MP4, resize for different channels and add comments.

   Canva's tools and limits page marks which tools every Canva user gets and which need Canva Pro, Business or Enterprise. Export works on every plan, with standard quality on Free and lossless PNG and transparent backgrounds on paid plans. Free users get a limited trial of image generation. There is a default cap of 300 requests a minute per user across all of that user's clients.

   What the list does not include is posting. Canva's documented tools end at export, so the design still has to reach Instagram or LinkedIn some other way. We cover the setup and the full tool list on our Canva MCP server page.

   Pros

   • Creates and edits real Canva designs
   • Uses your brand kits and templates
   • Exports to PDF, PNG, JPG, PPTX and MP4
   • Many tools work on a free account

   Cons

   • No posting tool in the documented list
   • Best export quality needs a paid plan
   • Brand consistency depends on how well your templates are set up
7. 7

   Ahrefs

   From $129 a month (Lite). Starter at $29 does not list MCP

   Best for backlinks, site audits and Search Console data from chat

   Ahrefs runs a hosted server at api.ahrefs.com/mcp/mcp. Ahrefs' MCP docs say it is available on paid plans from Lite up, and that each plan sets a maximum number of rows per request and a monthly allowance of API units, spent the same way as direct API use. You approve the connection on a consent screen and Ahrefs creates a dedicated key tagged with the MCP scope. New keys made this way default to 200,000 API units a month, which a workspace admin can change.

   Ahrefs' tool categories page splits the tools into groups you can choose with a parameter in the address: Site Explorer overviews and reports, Keywords Explorer, site audits, web analytics, Google Search Console keywords and pages, social media channel and post metrics, Content Helper, batch analysis and account management. Some clients cap how many tools a server may advertise, and Ahrefs exceeds that cap for many of them, so there is an essentials setting with a curated set. The docs list setup guides for Claude on web, desktop and mobile, Claude Code, ChatGPT, Copilot Studio, Lovable, n8n, Manus, Le Chat and OpenClaw.

   Ahrefs pricing lists Lite at $129 a month, Standard at $249 and Advanced at $449, each with API and MCP access. Starter at $29 does not list MCP. If you already pay for Ahrefs, the server costs nothing extra; if you are choosing between the two SEO tools, see the comparison further down.

   Pros

   • Hosted, with OAuth and a consent screen
   • Search Console and site audit data alongside backlinks
   • Tool groups you can trim for clients with small limits
   • Per key unit caps an admin can set

   Cons

   • Needs Lite at $129 a month or more
   • Every call spends API units
   • The docs do not say which tools change anything
8. 8

   Google Ads

   Free and open source. You pay for ad spend

   Best for reading Google Ads performance in plain words, without risk of changes

   Google's Ads team publishes the Google Ads MCP server in the googleads GitHub organization under Apache 2.0. Google's developer page is clear that this release is read only: it cannot change bids, pause campaigns or create new assets. It has three tools: list the accounts you can reach, run a Google Ads Query Language search for metrics, budgets and status, and look up metadata about a resource such as a campaign.

   You run it locally with pipx, or deploy it to Cloud Run, where Google OAuth protects it so that Claude and ChatGPT can reach it through custom connectors that use OAuth. Clients without OAuth get an error from the Cloud Run address and need the local setup. When we checked on October 28, 2026, the page was last updated October 16 and said developer tokens were sunset on September 9, 2026 and are no longer required; the project needs Explorer, Basic or Standard API access instead. The code is in the Google Ads MCP repository.

   For a marketer this is a reporting tool. Ask which campaigns spent most last week and what each conversion cost, and the assistant writes the query for you. Changing anything still happens in Google Ads.

   Pros

   • Official, open source and free
   • Read only, so it cannot spend or change anything
   • No developer token needed since September 2026

   Cons

   • Only three tools, all for reading
   • Local or Cloud Run setup, not a one click connector
   • Changes still happen in Google Ads
9. 9

   Amplitude

   Free plan with 2 million events a month includes MCP

   Best product analytics server for app makers, with MCP on the free plan

   Amplitude's hosted server lives at mcp.amplitude.com/mcp, with a separate address for EU data. Amplitude's MCP docs list tools that run segmentation, funnel and retention queries, fetch and create charts, get, create and edit dashboards, retrieve, create and sync cohorts (with a preview and a confirmation before a sync), work with experiments and feature flags, and manage your event taxonomy. It is not an ingestion endpoint, so it cannot send events.

   Sign in is OAuth with your Amplitude account. The server uses your existing permissions, and admins can block MCP for the organization. Each project has separate Use MCP read and Use MCP write permissions, and every role can read. Supported clients include Claude, Claude Code, ChatGPT, Cursor, Codex CLI, Gemini CLI, Replit, Lovable, Figma Make and Kiro. ChatGPT gets a curated subset of about 25 tools.

   Amplitude's pricing page lists the Free plan at 2 million events a month and includes AI agents and MCP on every plan. For an app team this is the server that answers which feature kept people coming back after the last release, which is often the post worth writing next. Our app retention benchmarks give the numbers to compare against.

   Pros

   • MCP on the free plan
   • Funnels, retention, cohorts and experiments from chat
   • Separate read and write permissions per project
   • EU data residency address

   Cons

   • ChatGPT gets only about 25 tools
   • Write tools can change your tracking plan, so limit who has them
   • Product data, not marketing channels
10. 10

    Klaviyo

    Free plan up to 250 active profiles. Klaviyo's MCP docs name roles, not a plan

    Best for email and SMS: campaign reports and new campaigns from chat

    Klaviyo recommends its hosted server at mcp.klaviyo.com/mcp, which uses OAuth with dynamic client registration. Klaviyo's connection guide says only users with an Owner, Admin or Manager role can use it. Claude has a listed Klaviyo connector and ChatGPT a Klaviyo app for single accounts, while a custom connector is the route for several accounts, which Klaviyo says is for Claude Pro, Max, Team and Enterprise users. Cursor and VS Code are documented too.

    The useful part is the set of switches you add to the address. One turns off every tool that can write to your Klaviyo account. Another hides tools that read customer written content, which Klaviyo flags as a prompt injection risk. Another loads only about 30 core tools for clients with small context windows, and another limits tools to the API scopes you list. The switches only work on a custom connector, not the listed Claude connector or ChatGPT app.

    Klaviyo's MCP page lists tools across campaigns, flows, profiles, reporting, catalogs and events, and says you can ask for campaign performance over a period, compare flows by conversions or create an email campaign. It does not say whether the server can send. Klaviyo's pricing has a free plan for up to 250 active profiles and 500 email sends a month.

    Pros

    • Hosted, with listed apps in Claude and ChatGPT
    • A switch that turns off every write tool
    • Can hide tools that read customer written content
    • Campaign and flow reports in plain words

    Cons

    • Owner, Admin or Manager role required
    • Safety switches need a custom connector
    • Sending behavior is not documented
11. 11

    TikTok for Business

    No price stated. You pay for ad spend

    Best for TikTok ads teams who want campaign work and reports in chat

    TikTok runs an official MCP server for its ads platform. TikTok's help article, last updated August 2026, describes tools for campaign management, performance reporting, audience configuration and creative operations, with examples such as creating campaigns, pulling performance reports, updating targeting, adjusting budgets and pausing ad groups. It says no developer credential, API key management or coding is needed.

    There are two loading modes. Full disclosure loads around 400 tools when you connect and is the one TikTok recommends for Claude. Progressive disclosure loads around 40 core tools and finds the rest on demand, which suits clients that struggle with long tool lists.

    The article does not describe permission scopes, approval steps or paused creation, and it says agents can run workflows without human intervention at every step. That is a reason to test on a small account first. This server buys and manages ads; for organic TikTok posting see our TikTok MCP server guide.

    Pros

    • Official TikTok server for the ads platform
    • Around 400 tools, or a lighter 40 tool mode
    • No developer credentials to manage

    Cons

    • No documented approval step or paused default
    • Price and availability not stated
    • Ads only, not organic TikTok posts

• Social Media Publishing

  Spreadcast. It designs the post in your brand, writes the captions, and publishes to Instagram, Facebook, Threads, LinkedIn, Pinterest, TikTok, YouTube, Bluesky, Mastodon, Telegram and Discord after you approve. For schedulers that only post what you bring, see the social media MCP roundup.

• Paid Social Ads

  Meta Ads for Facebook and Instagram, because it creates everything paused and documents the activate step. TikTok for Business if TikTok is where your budget goes.

• Website Analytics

  Google Analytics. Free, official and read only, at the cost of a local setup with Google Cloud credentials.

• App and Product Analytics

  Amplitude, with MCP on its free plan of 2 million events a month. It answers the retention and funnel questions that GA4 handles less well for apps.

• SEO Research

  Semrush if you want a listed app in Claude and ChatGPT and Trends data. Ahrefs if backlinks, site audits and Search Console data matter more and you want a cheaper entry plan.

• Design

  Canva for designs from your templates. Spreadcast when the design is a social post that should also be captioned and published.

• CRM and Leads

  HubSpot. Free on every tier, reads and writes records and tasks, and keeps your HubSpot permissions.

• Email and SMS

  Klaviyo, with a switch that turns off every write tool while you learn what it does.

From Semrush's developer docs, Semrush's knowledge base, Ahrefs' MCP docs and Ahrefs' tool categories, read October 28, 2026.

1. Step 1

   Measure Last Week

   With Google Analytics or Amplitude connected, ask for sessions, signups or installs by source for the last seven days compared with the seven before, and the top three pages or features. Write down the one number you want to move this week.

2. Step 2

   Pick the Topic

   With Semrush or Ahrefs connected, ask for five questions people search around that topic in your country, with volume. One of them becomes this week's post and, if you blog, this week's article.

3. Step 3

   Design and Caption the Posts

   With Spreadcast connected, ask for a carousel answering the question and two single image posts from your latest release, in your brand, with captions for each network. Check the previews in the chat and ask for changes in plain words.

4. Step 4

   Approve and Schedule

   Approve the drafts in Spreadcast or let the assistant approve them if you granted publishing access, and spread them across the week. They go to every connected network, including Threads, Bluesky and Telegram, which some schedulers do not support.

5. Step 5

   Boost What Worked

   On Thursday, ask Spreadcast's analytics which post got the most reach and interactions. If one stands out, ask the Meta Ads server to boost that Instagram post with a small budget. It arrives paused; read it, then activate it.

6. Step 6

   Follow Up

   Ask HubSpot for contacts created this week from social and create follow up tasks, or ask Klaviyo to draft a welcome campaign for the new signups. Review before anything sends.

1. Step 1

   Confirm It Is the Vendor's Own Server

   The address should be on the vendor's domain or its official GitHub organization, and linked from its own documentation. Directories list many lookalikes that ask for your API key.

2. Step 2

   Read What It Can Change

   Find the vendor's tool list and sort it into reads, writes and actions that go live or spend money. Use the table on this page as a starting point.

3. Step 3

   Prefer OAuth Over a Pasted Key

   OAuth lets you approve access on the vendor's own page, often pick a narrower scope and revoke it from a list. A key in a config file usually reaches everything and is easy to leak.

4. Step 4

   Start Read Only Where You Can

   Klaviyo's switch, Meta's minimum permissions, Google Analytics' read only scope and Spreadcast's drafts only access all let you learn the server before it can change anything.

5. Step 5

   Keep Confirmations On for Spending

   Leave your client's approval prompts on for anything that activates an ad, publishes a post or sends a message. Do not click Allow always on those tools.

6. Step 6

   Know How to Disconnect

   Find the page where the connection is listed before you need it, in the vendor's settings and in your assistant's connectors menu, so you can cut access in seconds.
