## Scores

| Criterion | Score | Evidence |
|-----------|-------|----------|
| Token Efficiency | 6/10 | Vercel provides REST APIs with standard pagination but lacks field selection capabilities and response compaction options, requiring agents to handle full payloads without granular filtering. |
| Programmatic Access | 7/10 | Vercel offers REST API, CLI, and SDKs in Node.js and Python, providing solid programmatic access, but lacks OpenAPI documentation, GraphQL alternative, and critically lacks an MCP server for agent integration. |
| Autonomous Auth | 8/10 | Vercel supports API tokens with scoped permissions and team/project-level access controls, enabling autonomous agent authentication without human-in-the-loop OAuth flows. |
| Speed & Throughput | 6/10 | No explicit rate limit information or conditional request support (ETags) visible in signals; response latency data unavailable, limiting assessment of concurrent request handling capabilities. |
| Discoverability | 4/10 | No OpenAPI spec available, no llms.txt or agents.json files, and robots.txt actively blocks agents; developer documentation exists but agent-specific guidance is absent, significantly hindering discoverability. |
| Reliability | 6/10 | Vercel maintains a public status page and offers consistent REST API responses, but lacks visible idempotency key support and API versioning strategy documentation in the collected signals. |
| Safety | 7/10 | Scoped API tokens and project isolation provide access controls; sandbox/staging environments exist for deployments, but explicit dry-run operations and undo capabilities are not evident. |
| Reactivity | 7/10 | Vercel provides deployment webhooks and real-time event notifications, enabling agents to react to state changes, though streaming APIs and SSE are not documented in available signals. |

## Biggest Friction

The absence of an OpenAPI specification, MCP server, and agent-discovery files (llms.txt/agents.json) combined with robots.txt blocking agents creates significant friction for autonomous AI agent discovery and integration.
