Best for
- Automation and CI scenarios that need headless token auth (Notion's hosted MCP is OAuth-only)
- Agents where context/token cost matters (only 422 tokens of tool schema at connection)
- Workflows needing batch mutations, idempotency, retries, and rate limiting
- Self-hosted deployments and developers exposing their own HTTP endpoint
- Users of any MCP-speaking client (Claude, Cursor, VS Code, Cline, Zed, Continue, etc.)
