xmark syncs your X bookmarks and lets you chat with them. Tools: list, get, and semantic-search your bookmarks; sync new bookmarks from X; chat with your bookmarks and get answers that cite them; list past conversations and their messages; check usage and the API changelog. Two sensitive tools (Muse asks first): delete_conversation permanently deletes a chat, and delete_bookmark removes a bookmark from xmark and, with unbookmark on, from X too. Nothing is published or sent. Needs an xmark account with X connected and an API key. Free: 20 chats a month, 1 sync a day; pro removes the limits.

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use xmark to help me. It is a free service with an MCP server at https://api.xmark.dev/mcp. It needs an API key from JCLVSH LLC; ask me to enter it through your secure credential prompt. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.
