Mailchimp MCP Server
cyanheads · MCP server
Connects your AI assistant to a Mailchimp account through the Mailchimp Marketing API. Your agent can draft an email campaign, send a test, then send or schedule it once you confirm, manage audiences and subscribers, import subscribers in batches of up to 500 that are pending by default, and read post-send reports. Local template and image folders can be used when writing campaign content. It runs on your machine and needs a Mailchimp API key.
Written by ooruby from the README of @cyanheads/mailchimp-mcp-server 0.3.11.

Why it's useful
Your agent can take a campaign from first draft through sending to its results report, working directly in your Mailchimp account.
What you could do with it
- Turn a URL or a brief into a newsletter, send yourself a test, then schedule it for later.
- Find a subscriber by email across your audiences, then update their tags or add a note.
- Pull the post-send report of a campaign and have your agent summarise its top links and unsubscribes.
Written from its documentation: what it says it can do, not what our checks found.
Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured
What this does not cover
- Everything. Treat it as you would software from anywhere else.
Receipt history: every signed receipt for every version of this listing, and what changed between them.
In its maker's words
Draft, test, and send Mailchimp campaigns straight from your MCP client — with audience management, subscriber CRUD, and post-send analytics behind safe-by-default send gates. STDIO or Streamable HTTP.

- What it establishes
- Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
- What it does not
- How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
- Exactly what was read
- Version 0.3.11, the file with digest sha512-1pT6uLZati2OAYVQy9RgHHQkPU/qQ0d/c149QwwZ1E4iEhjh0QHdEW8IQuXR8PCHnHrqYstl9sIxXJzUcNPrqw==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
Adding it
Paste this into your client's MCP configuration.

No build provenance published. The repository above is the one the publisher declared, and nothing links it to the package you would install. That is not a mark against this listing, since most packages are published this way, but it is a check nobody can run.
The badge, if this is your listing
It renders the current rung (static scanned) and links back here, where what that does and does not establish is one click away. It updates itself as the evidence deepens.
