mcp-server-outline

MCP server for the Outline knowledge base / wiki API. Works against any self-hosted or cloud Outline instance (we run it against our "Playbook" instances).

Tools

Read: outline_search (ranked full-text with context snippets; filter by collection/status/date/author), outline_list_documents (recent/drafts/archived/trash), outline_get_document (info or full Markdown export), outline_list_collections, outline_get_collection (+ document tree), outline_list_comments, outline_list_revisions, outline_whoami, outline_search_capabilities.

Write (opt-in via OUTLINE_ENABLE_WRITES=true): outline_create_document, outline_update_document (replace or append), outline_move_document, outline_archive_document (archive/restore), outline_delete_document (soft-delete to Trash only), outline_create_comment, outline_manage_collection (create/update).

Deliberately not exposed: collections.delete (cascading permanent delete of every document inside), permanent document deletion / documents.empty_trash, and user deletion. Document deletion is always the recoverable soft-delete.

Auth

Bearer API token (Outline → Settings → API → Create). The token inherits its creating user's document/collection permissions — create a dedicated service user per instance with the right collection access. Tokens are per-instance.

Configuration

See .env.example. Required: OUTLINE_BASE_URL (the server appends /api), OUTLINE_API_TOKEN.

Run

npm install
npm run dev          # stdio
npm run dev:http     # streamable HTTP on :3000/mcp (stateless)
npm test
