Read and write to the Fediverse inside Claude Desktop

This MCP Server lets your local Claude Desktop app pull your feed using `get_home_timeline` and publish updates using `post_status`. You don't have to keep a browser tab open to watch the Fedi anymore; your agent handles it. If a Fedi post catches your eye, tell Claude to run `reblog_status` or `favourite_status` to interact. It runs directly through your local app's stdio connection, keeping your auth keys safe on your own machine.

Track trends and search Mastodon instances

This Mastodon MCP Server tracks trends and searches decentralized networks directly from your Claude Desktop workspace. Ask your agent inside Claude Desktop to run `get_trending_tags` or `get_trending_statuses` to see what topics are gaining traction. You can also use `search` to dig up specific accounts or hashtags across the Fedi. Claude Desktop processes the raw JSON and gives you a clean summary without the noise of the official web interface.

Manage media and files from your local machine

This media-handling MCP Server lets Claude Desktop grab images from your hard drive and use `upload_media` to send them to your Mastodon instance. No more manual dragging and dropping. After uploading, your local Claude agent can use `update_media` to add descriptive alt text for accessibility before you publish. It makes posting rich content to the Fediverse a single-step chat command.
