## Scores

| Criterion | Score | Evidence |
|-----------|-------|----------|
| Token Efficiency | 6/10 | API responses likely include standard authentication and user data payloads, but without an OpenAPI spec or documented field selection capabilities, it's unclear if the API supports sparse fieldsets or efficient pagination patterns. |
| Programmatic Access | 7/10 | Stytch offers REST API access with official SDKs in Node.js and Python, plus framework-specific integrations (Next.js, Hono, Cloudflare Pages), providing solid programmatic coverage, but the absence of an MCP server and OpenAPI spec limits discoverability and agent-native tooling. |
| Autonomous Auth | 8/10 | Stytch is an auth provider itself, and the signals indicate API key-based authentication is supported via SDKs without apparent OAuth-only restrictions; autonomous agent authentication should be straightforward with properly scoped API keys. |
| Speed & Throughput | 6/10 | No response time data collected, rate limits undocumented in provided signals, and no mention of ETags or conditional request support, making it difficult to assess latency performance or optimization for concurrent agent requests. |
| Discoverability | 5/10 | Developer documentation exists and robots.txt allows agent crawling, but the absence of OpenAPI spec, llms.txt, or agents.json means agents must rely on web documentation scraping rather than machine-readable API contracts. |
| Reliability | 7/10 | As an authentication provider, Stytch likely maintains strong API versioning and consistency standards (inferred from maturity: NPM packages at v13+, Python at v14.2), but no explicit mention of idempotency keys or status pages in the signals. |
| Safety | 7/10 | Stytch's core function as an auth provider implies sandbox/test mode support and scoped credential tokens, but the signals don't confirm explicit dry-run modes or undo capabilities for agent-initiated operations. |
| Reactivity | 5/10 | No mention of webhooks, streaming, or SSE in the collected signals, suggesting agents must rely on polling for real-time event detection, which is less efficient than push-based reactive patterns. |

## Biggest Friction

The absence of an OpenAPI specification and machine-readable API contract (llms.txt/agents.json) forces agents to rely on web documentation scraping rather than autonomous API discovery and type safety.
