Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

[!WARNING] This project is no longer maintained as Outline has launched its own official MCP server with OAuth support. You should use that.

•

A Model Context Protocol (MCP) server that provides tools for interacting with Outline's API, enabling AI agents to manage documents, collections, and other entities programmatically through the Outline knowledge base platform.

Connect

Built from this server's own package name, version and transport as found in its source — not copied from anyone's documentation, so it cannot drift against a page we do not control. Replace the environment placeholders with a token scoped to the least it needs.

Questions

What is the Outline MCP server?

It's an MCP server... for Outline (the documentation platform!)

What tools does Outline expose?

19 in total: 9 read-only, 8 that write, and 2 that can delete or overwrite (delete_comment, delete_document). Every one is listed on this page with its risk.

Is Outline safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B. Separately from the audit: 2 of its tools can destroy data, so scope the token you give it to what you actually need.

What credentials does Outline need?

It reads OUTLINE_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How does Outline run?

It speaks sse, stdio and streamable-http, so it runs as a local process your client starts. It is published on npm as outline-mcp-server at 5.8.5.

How current is this page?

The grade is for one exact copy of the source (c485de71d4ce), read on 2026-10-07. The repository is watched and re-audited when it changes.
