## Which one, for what

### monday.com (BB)

Good for: Teams that already run projects on monday.com boards and want an agent to create items, change status, post updates and read board summaries through MCP or GraphQL.

Ahead on:
- Reliability, 79 against 52
- Schema & documentation, 88 against 76
- Agent ergonomics, 82 against 70
- Security & auth, 70 against 59
- Payments & pricing, 50 against 30
- Maintenance & community, 85 against 75

Also in its favour:
- Agent-ready, a grade of BB or better
- A hosted endpoint, with nothing to install
- No incidents deducted, where OpenProject loses 5 points for them

Watch for: Personal API tokens have no scopes. Each carries every permission its user has in the app

### OpenProject (C)

Good for: Teams that want a self-hostable or EU-hosted project tool with Gantt, time tracking and budgets, and an agent working through a documented REST API.

Ahead on:
- Transparency & trust, 87 against 80

Also in its favour:
- Open source

Watch for: 83 advisories published against opf/openproject in the twelve months to 8 October 2026, 13 rated critical, among them remote code execution and SQL injection

## Verdicts

**monday.com.** The GraphQL API publishes its full schema, accepts an `Idempotency-Key` header on mutations and reports limits in `RateLimit` headers, and a documented signup API lets an agent create its own account and token. Personal tokens carry every permission their user has, daily calls stop at 1,000 below Pro, and the status page shows two long platform incidents since July 2026.

**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.

## Before you call either

### monday.com

1. Send an `API-Version` header such as 2026-10 on every call. Without it the API uses whichever version is current
2. Read the board's columns first (`get_board_info` or `boards { columns }`), then write column values as a JSON string keyed by column ID
3. Reuse one `Idempotency-Key` per mutation when retrying after a timeout or 5xx. After a 429, wait for `Retry-After` or `retry_in_seconds`
4. Page items with `items_page` and `next_items_page`, at most 500 a page. Cursors expire after 60 minutes
5. For a narrower grant than a personal token, connect MCP through a custom OAuth app with only scopes such as `boards:read`

### 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
