The markdown workspace your AI can read, search, and suggest edits in — every change signed.
Most developer tooling work still happens through a UI a human drives. Syncpen MCP server moves it into the conversation instead. The markdown workspace your AI can read, search, and suggest edits in — every change signed.
The server publishes 14 tools. What each one is for:
syncpen_search — Search documents by title and body content (full text)syncpen_read — Read a document's content as markdownsyncpen_list_folders — List all folderssyncpen_list_documents — List documents, optionally by foldersyncpen_create — Create a new documentsyncpen_update — Update a document's title and/or contentsyncpen_suggest_edit — Propose an edit as a pending suggestion a human accepts/rejects (doc unchanged until accepted)syncpen_list_suggestions — List a document's pending (or all) suggestionssyncpen_list_comments — Read comment threads (with replies, line numbers, authors)syncpen_reply_comment — Reply to a comment thread (signed, notifies @mentions)syncpen_resolve_comment — Mark a comment thread resolvedsyncpen_move_document — Move a document into a folder, or to the rootConfiguration is passed through the environment: SYNCPEN_API_KEY, SYNCPEN_API_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
The server ships on npm as npm, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Syncpen's toolset — syncpen_search, syncpen_read, syncpen_list_folders and 11 more — is a fair guide to whether it matches your workflow. It is maintained by airbuzz; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
