HonestClaw · What is Agent Readiness? · How we score
Strong. Agents can discover and use most of this site unaided.
HonestClaw measured initial public content available from stripe.com to an identified HTTP agent, without browser rendering or login, across 9 dimensions and 42 automated checks. This does not measure access from another agent provider's infrastructure. Score: 71/100 (Strong).
Scanned · scanner v1.70.5 · 41 of 42 checks conclusive.
6 of 8 scored areas have measured gaps. Access & rendering is furthest along; Interfaces & data has the largest measured point gap.
89 additional observations provide context and do not affect the score.

Observable state and actionable errors help recovery. A status page or error schema does not prove successful repair.
These sources inform the check. They do not validate our exact point weights.

Actionable limits
Rate limits are documented at https://docs.stripe.com/rate-limits with a concrete limit and rate-limit response headers. To reach the top level, it would need 429 handling, Retry-After guidance, and tier/plan differences.
These are recorded points before the total is normalized to 100.
An interface with quotas or throttling
Published limits and response headers help clients pace requests and recover from throttling. They describe related aspects of the same service constraint.

Additional GraphQL recovery evidence
No GraphQL endpoint was observed in a scanner-fetched declaration or GraphQL-shaped response. GraphQL depth probe: No GraphQL endpoint was observed in a scanner-fetched declaration or GraphQL-shaped response.

Instruction-safe interaction surfaces
Accessibility-tree probe unavailable (deep_scan_only): Accessibility-tree checks are deep-scan only to avoid always-on browser probe cost.
A limited scanner observation, not proof of access from real agent infrastructure. It remains unscored until the probe can support that claim.
Deep scans with an available browser accessibility tree snapshot
Prompt-injection-like instructions in accessibility text are a real manipulation risk for agent operators. This bounded probe can surface risky text but cannot prove complete absence, so it remains unscored.

Application isolation declarations
No adoption signal was detected, but endpoint discovery was incomplete or at least one declared MCP endpoint lacked readable list metadata, so site-level absence is unmeasurable. This metadata-only check did not call tools or read app resources.
An emerging convention, not a universal requirement. It adds no points and its absence subtracts none. Adoption and reliable testing must justify any future weight.
Detected MCP application UI
Declared origins and CSP are relevant safeguards for an embedded UI, but declarations alone do not establish effective isolation.
