Summary
Pulls public data from mastodon.social without authentication, giving you three tools: get_trending for popular posts and tags, get_timeline for the public firehose, and get_account for profile lookups by ID. Part of the Pipeworx gateway ecosystem, so you can either point directly at this endpoint or connect to their full gateway for 673+ sources. Useful when you need to sample Mastodon sentiment, track trending topics, or grab public profile data without dealing with OAuth. The ask_pipeworx wrapper lets you query in plain English instead of calling tools directly.

Part of Pipeworx — an MCP gateway connecting AI agents to 1476+ live data sources.
Tools
| Tool | Description |
|---|---|
search | Search Mastodon for accounts, statuses, or hashtags. Returns matching profiles, posts, and tags with follower counts and engagement metrics. |
get_trending | Get currently trending posts on Mastodon. Returns popular statuses with engagement counts, authors, and trending tags. |
get_account | Get a Mastodon account profile by ID (e.g., '109382839472938472'). Returns bio, follower/following counts, post history, and verification status. |
get_timeline | Get recent posts from the public Mastodon timeline. Returns statuses with authors, timestamps, engagement counts, and content. |
Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"mastodon": {
"url": "https://gateway.pipeworx.io/mastodon/mcp"
}
}
}
What this endpoint actually serves
tools/list at https://gateway.pipeworx.io/mastodon/mcp returns the tools in the table
above plus the shared Pipeworx meta-tools — ask_pipeworx,
discover_tools, search_within, remember/recall and the rest of the
gateway-wide set. So the tool count you see is larger than this table: a
single-pack endpoint currently lists roughly 30 shared tools alongside the
pack's own. The connection's initialize response states its exact scope, and
is the authoritative answer for a given day.
This is deliberate, not multiplexing by accident. The meta-tools are what let a
scoped connection answer a question this pack does not cover — via
ask_pipeworx, which routes across the whole catalog — without you adding a
second MCP server. There is currently no way to mount a pack endpoint without
them; if the extra schemas cost you more context than the routing is worth,
connect to the full gateway once rather than to several pack endpoints.
Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Both URLs reach the same gateway and the same 1476+ data sources. The
only difference is which pack's tools are listed directly; ask_pipeworx
reaches all of them from either one.
Using with ask_pipeworx
Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:
ask_pipeworx({ question: "your question about Mastodon data" })
The gateway picks the right tool and fills the arguments automatically.
