## Scores

| Criterion | Score | Evidence |
|-----------|-------|----------|
| Token Efficiency | 2/10 | No OpenAPI spec, no field selection capability visible, and no documentation of pagination or batching mechanisms indicate poor token efficiency for API interactions. |
| Programmatic Access | 2/10 | Only basic SDK support in 2 languages (Node/Python), no REST API documentation found, no GraphQL, no CLI tool, and critically no MCP server available for agent integration. |
| Autonomous Auth | 3/10 | SDKs exist but authentication mechanisms are undocumented; without visible API key documentation or auth examples, autonomous agent authentication is unclear and likely requires manual setup. |
| Speed & Throughput | 2/10 | No rate limit documentation, no ETag support visible, no async/concurrent request documentation, and response time metrics are unavailable, suggesting poor visibility into performance characteristics. |
| Discoverability | 1/10 | No OpenAPI spec, no developer docs on homepage, no llms.txt or agents.json files, and minimal structured data make it nearly impossible for agents to discover how to use this tool. |
| Reliability | 2/10 | No visible API versioning, no documented idempotency keys, no status page reference, and no consistent response schema documentation suggest unreliable integration patterns. |
| Safety | 1/10 | No sandbox/test mode documented, no dry-run capability visible, no scoped access tokens mentioned, and no undo mechanisms evident for destructive operations. |
| Reactivity | 1/10 | No webhooks, streaming, SSE, or polling mechanisms documented; the tool appears to offer synchronous SDK access only with no event-driven capabilities. |

## Biggest Friction

Complete absence of OpenAPI documentation, MCP server support, and public API specification makes it impossible for agents to autonomously discover and integrate with Heap's services.

## Access Methods

- SDKs: Node (@datastructures-js/heap), Python (heap)
