Nearly every tool in a marketing stack now runs its own official MCP server: HubSpot, Salesforce, Klaviyo, Canva, Webflow, Notion, Semrush, PostHog, Meta and TikTok among them. The question has moved from whether a server exists to two others — what it can change, and what each call costs. This list answers both for every job in the stack, and names the gaps that are left.
Last updated September 21, 2026. Sprites is on this list and we build it; the entry says so. On Claude specifically, the connector shortlist is the narrower version. New to the protocol? What MCP is.
The short answer, by job
| Job | Start with | Why |
|---|---|---|
| Paid media | Sprites | Every channel behind one endpoint, including LinkedIn and Reddit, with changes held for approval |
| Research | Semrush or Ahrefs | The deepest data; both metered |
| Product analytics | PostHog | Hosted, writes, free to call |
| Site | Webflow or WordPress | Official, write-capable |
| Lifecycle | Klaviyo or HubSpot | Official; set read-only first |
| Creative | Canva | Generate and export on every plan |
| Context | Notion | Where the brief already is |
Paid media
Twelve months ago this was the category with no official servers. Now seven ad platforms run one and four of them can change campaigns — each on its own platform only. The full comparison, with what each one takes to connect, is in the best MCP servers for paid ads. Google’s own server reads but cannot change anything; the Google Ads MCP guide sets it beside the community servers and a connector that writes behind an approval.
Sprites
Ours, so read it with that in mind. Sprites is an AI marketing agent, and its MCP server puts Google Ads, Meta, LinkedIn, TikTok, Reddit, GA4, Search Console and your CMS, Shopify and Google Business Profile behind one URL. It does something the vendor servers on this page do not: it decides. Ask where budget is being wasted and it reads the accounts, does the analysis and returns changes with reasons, each one an approval card you edit before anything applies. The doors are broad — analyze, optimize, launch, change — so the tool list stays short.
Remote · read and write, approval-gated · plan credits, no API units
Research and SEO
The most mature corner of the category, and the most metered: every serious research server bills per call in its own API units or credits.
Semrush
Keywords, domains, backlinks, paid and shopping research, plus traffic with a Trends subscription. Starter and Pro+ include 50,000 MCP API units a month, spent per row returned — about 20,000 on one competitor workup. Semrush MCP, in full.
Remote · read only · source
Ahrefs
Keywords, backlinks, competitor traffic and content gap, on Lite and above. Every call costs at least 50 API units. Ahrefs MCP, in full.
Remote · read only · source
Similarweb
Traffic, audience, keyword and competitor data on API-only, Business or Enterprise plans, spending the same data credits as the API. Connects with an API key rather than OAuth.
Remote · read only · source
DataForSEO
SERP, keyword and backlink data with no MCP fee: you pay pay-as-you-go API rates for what the assistant pulls. The cheapest raw data in the category, and the most assembly required.
Remote · read only · source
Analytics and product data
Where the biggest change happened. Product-analytics vendors shipped hosted servers that write — dashboards, cohorts, feature flags — while Google’s own GA4 server is still a local, read-only package.
Google Analytics
Google’s GA4 server: reports, funnels, realtime and account summaries. Still labelled experimental, read-only, and it runs on your machine. GA4 through a hosted connector is the alternative.
Local · read only · source
PostHog
Insights, dashboards, SQL, feature flags, experiments, surveys and error tracking, one endpoint for US and EU. Free to call; tools that use an LLM internally bill as PostHog AI. PostHog through Sprites, compared with PostHog’s own server.
Remote · read and write · source
Mixpanel
More than 60 tools across queries, dashboards, cohorts and experiments. Capped at 600 requests an hour per user, and not covered for HIPAA. Mixpanel MCP, in full.
Remote · read and write · source
Amplitude
Charts, dashboards, cohorts, experiments, flags and session replays, US and EU endpoints, free for existing customers. Amplitude MCP, in full.
Remote · read and write · source
Supermetrics
More than 170 marketing sources in one query, with beta campaign writes that are off until you enable them per account.
Remote · limited writes · source
CMS and publishing
Every major CMS except Framer and Ghost now has an official server, and most of them write. The question for an SEO is what stands between a model’s edit and the live page. For Framer, which ships none, Sprites writes to the Framer CMS as drafts you approve.
WordPress
Self-hosted sites use the official MCP Adapter over the Abilities API in WordPress 6.9, scoped to the signed-in user’s role. WordPress.com has its own hosted server, which gained post and page writes in March 2026, each confirmed by the user. The full path is on WordPress over MCP.
Self-hosted · read and write · source
Webflow
CMS items, pages, SEO metadata, assets and custom code; canvas work needs the Designer open. One authorization covers one workspace. Webflow through Sprites, compared with Webflow’s own server.
Remote · read and write · source
Contentful
Creates, updates, publishes and unpublishes entries and assets once the Contentful MCP app is installed in the environment, where an admin chooses read-only or read-write per tool category.
Remote · read and write · source
Sanity
Hosted at mcp.sanity.io: documents, schema, GROQ queries, datasets and releases, scoped to the permissions of the token you connect with.
Remote · read and write · source
No official server: Framer, Ghost.
Ecommerce and revenue
Commerce split into a public storefront surface anyone can query and an admin surface that only arrives through the platform’s own assistant apps.
Shopify
Every store answers at {shop}.myshopify.com/api/mcp with no authentication: catalogue search, cart and policy questions. The merchant side — products, inventory and discount codes, with orders and customers read-only — comes through Shopify’s own connector for Claude. Shopify over MCP.
Remote · limited writes · source
Google Merchant Center
An alpha, hosted server for products, account issues and reports, on your normal Merchant API quota.
Preview · limited writes · source
Stripe
Turns "our ROAS" from a platform-reported number into a comparison with money that arrived. Grant read-only scopes unless you have a reason not to.
Remote · read and write · source
CRM and lifecycle
The fastest-moving job. HubSpot and Salesforce went GA in April 2026, and the email platforms went further than anyone expected: Klaviyo’s server can send a campaign.
HubSpot
Writes contacts, companies, deals and tickets; reads campaigns, landing pages and blog posts; blocks sensitive properties entirely. HubSpot MCP, in full.
Remote · read and write · source
Salesforce
Hosted MCP servers on every Enterprise Edition org and above, running as the signed-in user with their field-level security and sharing rules. Usage bills against Flex Credits, and an admin activates each server.
Remote · read and write · source
Klaviyo
More than 260 tools, including send_campaign. A read-only switch exists, and it is the first thing to set. Klaviyo MCP, in full.
Remote · read and write · source
Customer.io
Creates and edits campaigns, segments and broadcasts. By default it cannot delete people or touch live automations; an admin can switch on editing live data.
Remote · read and write · source
Apollo.io
Search, enrichment, sequences and CRM records on every plan including Free, with enrichment spending your plan’s credits; prospecting Apollo’s full database needs a paid plan.
Remote · read and write · source
Creative
The most tightly metered corner: per-minute limits on every Canva tool, per-day limits on Figma reads.
Canva
Generate, edit, comment and export on every plan; resize and brand kits need a paid plan; autofill needs Enterprise. Canva MCP, in full.
Remote · read and write · source
Figma
Dev and Full seats get up to 200 read calls a day on Professional and Organization plans and 600 on Enterprise; view and collab seats get a few a month. Tools that write to files are exempt from the limits.
Remote · limited writes · source
Adobe
The Adobe for Creativity connector in Claude brings more than 50 tools across Photoshop, Lightroom, Illustrator, Firefly, Premiere, Express, InDesign and Stock. About 40 work with no Adobe account at all.
Remote · read and write · source
Social
Scheduling tools now ship servers. The networks themselves mostly do not: X has one; LinkedIn has apps inside ChatGPT but no server other clients can reach; YouTube and Reddit have nothing. The routes that exist are in LinkedIn MCP and Reddit MCP.
Buffer
Reads your channels, queue and drafts, schedules and edits posts, and pulls analytics, on every plan including Free. Posts land in your Buffer queue, so nothing publishes unseen.
Remote · read and write · source
Hootsuite
Three servers live — Perch for publishing, Nest for the inbox, Lumen for read-only listening — with Parliament, for employee advocacy, to follow.
Remote · read and write · source
X
Hosted at api.x.com/mcp: post search, users, bookmarks, trends and articles, billed pay-per-use through the X API.
Remote · read and write · source
No official server: LinkedIn (ChatGPT only), YouTube, Reddit.
Where the brief lives
The cheapest quality upgrade in any stack. Everything else writes better once it has read the positioning doc.
Notion
Search, read, create and update pages and databases, with rate limits shared across your workspace’s connections. Notion MCP, in full.
Remote · read and write · source
Slack
Search messages, files, people and channels, read threads, send messages and create canvases. Generally available.
Remote · read and write · source
Google Workspace
Managed servers for Gmail, Drive, Docs, Sheets, Slides, Calendar and Chat, in Google’s developer preview and enabled in your own Cloud project.
Preview · read and write · source
The escape hatch
For the tool nobody built a server for. Each one bills differently, and all of them bill per call in some form.
Zapier
9,000+ apps; two tasks per successful call, from the same quota as your zaps. The arithmetic.
Remote · read and write · source
n8n
Exposes the workflows you enable as tools; free with unlimited executions when self-hosted. Full comparison.
Self-hosted · read and write · source
Make
Runs your scenarios as tools on every plan, including Free, spending the usual credits per run; managing scenarios needs a paid plan.

What a call costs
The part most lists leave out. Connecting a server is almost always free; calling it is metered in the vendor’s own unit, and an agent calls far more often than a person clicks.
| Server | Metered in | Allowance or limit |
|---|---|---|
| Semrush | API units per row: 10 per keyword row, 40 per backlink | 50,000 units a month on Starter and Pro+ |
| Ahrefs | API units: at least 50 per call | Plan allowance; top-ups on Enterprise only |
| Zapier | Two tasks per successful call | Your plan’s task quota, shared with zaps |
| Mixpanel | Rate limit, not a price | 600 requests an hour per user |
| Canva | Rate limit per tool | 20–100 requests a minute; some tools paid-plan only |
| Figma | Daily cap on read calls, per seat | Up to 200 a day on Professional and Organization, 600 on Enterprise |
| Pipedream | Compute credits | 1 credit per 30 seconds, minimum 1 per call |
| DataForSEO | Pay as you go | Per request, from a prepaid balance |
| X | API credits | X’s pay-per-use pricing |
| Sprites | Plan credits | Included in every paid plan; no API units |
Two consequences. A conversation that fans out — "compare us with three competitors" — can spend a meaningful share of a monthly allowance on one question. And a rate limit shows up as a model that stops mid-task, which looks like the model failing rather than the meter.
Four stacks that work
- Performance marketer: Sprites for every ad channel, PostHog or Mixpanel for what the traffic did, and Notion for the brief.
- SEO lead: Semrush or Ahrefs for the market, Sprites for Search Console and the CMS, and nothing else. More on the SEO stack.
- Lifecycle and ecommerce: Klaviyo in read-only mode, Shopify, and Stripe for the revenue that actually arrived.
- Founder doing everything: Sprites, Notion and Canva. The order to add them in is in MCP for startup marketing.
What the registry actually holds
For scale, the official MCP registry held 31,793 distinct servers on September 14, 2026.
A registry entry is a published manifest, not a maintained product. The servers on this page are the ones a vendor stands behind.
Five questions before you connect one
- Remote or local? Local means installing software and keeping a credential in a file. Decide that on purpose.
- Can it write, and what gates the write? The specification defines no approval step. Meta and X create campaigns paused; Klaviyo offers a read-only switch; Sprites holds every change as an approval card. Others apply what the model sends.
- What does a call cost? Units, tasks, credits or a rate limit — see the table above — and an agent calls more than you think.
- How many tools does it expose? Hundreds of tools is hundreds of descriptions the model reads every turn. Prefer servers with a core-tools mode.
- What does the consent screen ask for? Anthropic’s advice is to "only connect to trusted servers" because a hostile one can hide instructions in its tool descriptions (Anthropic).
The deeper guides
- Paid ads: every ad platform’s own server, which can write, and what each takes to connect.
- SEO: research, Search Console and CMS servers, and the join none of them do.
- Startup marketing: the smallest stack that covers paid, organic and revenue.
MCP server questions
What is the best MCP server for marketing?
There is no single one, because no vendor’s server sees past its own product. A working marketing setup is three or four: something for the ad accounts, something for research data such as Semrush, something for the site or CRM, and wherever the brief is written. Sprites covers the ad accounts and the site from one endpoint.
How many MCP servers are there?
The official MCP registry listed 31,793 distinct servers on September 14, 2026. 19,332 publish a remote endpoint you connect to with a URL; 12,461 are packages you install and run yourself.
Do ad platforms have official MCP servers?
Most do now. Seven ad platforms run one, and four of those can change campaigns. LinkedIn has only a read-only app inside ChatGPT, and Reddit has nothing. The full map is in our paid-ads roundup.
What is the difference between a local and a remote MCP server?
A remote server runs on the vendor’s infrastructure: you paste an HTTPS URL, sign in with OAuth, and it works from any device. A local server is a package you install on your own machine, usually with an API key in a config file, and it works only there.
Do MCP servers cost money?
The server is usually free and the calls usually are not. Semrush and Ahrefs spend API units, Zapier spends two tasks per call, Pipedream spends compute credits, and Canva, Figma and Mixpanel cap how often you can call. Budget for the calls, not the connector.
How many MCP servers should I connect at once?
Three or four. Every connected server adds its tool descriptions to every turn, and some are large — Klaviyo has more than 260 tools, TikTok’s flat server about 400. Past a few dozen tools the model picks worse and every message slows down.
Are MCP servers safe to connect to business accounts?
It depends on the server. The protocol defines no approval step, so whether a write waits for you is each server’s decision. Anthropic warns that malicious servers "may include hidden instructions", so treat connecting one like installing an app with account access, and prefer read-only modes where they exist.
