Reviewer Notes

Notion has solid API documentation and OpenAPI specs, making discovery straightforward for agents. The API is well-structured with good error handling and reasonable rate limits (3 req/sec). However, account creation requires OAuth2 or manual API key generation—agents cannot fully self-onboard. The free tier limits are restrictive for autonomous agents (max 100 blocks/read, limited database operations), and no official MCP server exists, which is a notable gap. Reliability is solid with 99.9% uptime reputation.
