## Scores

| Criterion | Score | Evidence |
|-----------|-------|----------|
| Token Efficiency | 6/10 | Notion API supports filtering and sorting but lacks comprehensive field selection capabilities, requiring agents to fetch full block objects and parse unnecessary data; pagination is available but response sizes can be substantial for complex pages. |
| Programmatic Access | 8/10 | Notion offers a well-documented REST API with official SDKs in Node.js and Python, an official MCP server (notion-mcp-server v2.2.1), multiple community packages, and a CLI—providing multiple programmatic access paths for agents. |
| Autonomous Auth | 8/10 | Notion supports API key authentication with scoped OAuth permissions and integration tokens, enabling autonomous agent authentication without human-in-the-loop interaction. |
| Speed & Throughput | 6/10 | Homepage response is substantial (192KB) with no indication of response time metrics; rate limits exist but are not exceptionally generous, and no ETags or conditional request support is evident from the signals. |
| Discoverability | 7/10 | Notion provides an llms.txt file (6914 bytes) for AI agent discoverability and documents agent mentions on the homepage, but lacks an OpenAPI spec; REST API documentation is solid but not exceptional. |
| Reliability | 7/10 | Notion API supports versioning and maintains consistent response schemas, but signals don't confirm idempotency key support or a public status page, which are important for reliable agent operations. |
| Safety | 5/10 | Notion offers scoped OAuth tokens and read/write permission differentiation, but lacks explicit sandbox mode, dry-run capabilities, or operation undo mechanisms that would give agents safe testing and recovery options. |
| Reactivity | 4/10 | No evidence of webhook support, streaming, or server-sent events in the signals; agents must rely on polling-based approaches to detect changes, which is inefficient and introduces latency. |

## Biggest Friction

Absence of webhooks and real-time event streaming forces agents into inefficient polling patterns, and lack of field selection in API responses creates unnecessary token overhead for complex workspaces.
