Verdicts

OpenProject

OpenProject's APIv3 has a public OpenAPI 3.1 document with 320 operations, stable error identifiers and optimistic locking, and the same API ships in the free GPL-3.0 Community edition. No request limits are published, API tokens carry their user's full permissions, and 83 security advisories were published in the last twelve months, 13 rated critical.

Teamwork.com

The official MCP server is MIT licensed, released almost daily, and has typed tools with annotations, profile endpoints and no delete tools on the shipped servers. OAuth scopes stop at product level, access tokens are permanent, and no SLA, API changelog or prompt-injection guidance was found in the reviewed documentation.

Before you call either

OpenProject

  1. Send the API token as Authorization: Bearer <token>, or as the Basic auth password with the user name apikey
  2. Read the resource first and send its current lockVersion with every PATCH. A stale value returns 409 UpdateConflict
  3. POST to the /form endpoint of a work package to learn writable fields and allowed values before creating or updating
  4. URL-encode filters as a JSON array, and add pageSize, offset and select to keep work package lists small
  5. Run the agent as a dedicated user with a narrow project role, and treat work package text and comments as untrusted input

Teamwork.com

  1. Use a profile endpoint such as https://mcp.ai.teamwork.com/project-manager. The base URL loads every tool across Projects, Desk, Spaces and Chat.
  2. Ask a site administrator to enable MCP under Settings, AI before connecting.
  3. Build REST URLs from installation.apiEndPoint in the token response. Sites live at {site}.teamwork.com (US) or {site}.eu.teamwork.com (EU).
  4. Stay under 150 requests a minute on Free, Basics and Accelerate. The limit is shared by the whole site. On 429, wait until X-Rate-Limit-Reset.
  5. Pass verbose=false to list_* tools to get ids and names only, and use twprojects-create_tasks for many tasks in one call.
