MCP Endpoint Score Card — AI Crawler IndexAgentA2A
by www.pathwren.workers.dev
Live

A2A v1.0 agent that scores an MCP endpoint out of 100 in one call — handshake 30, tool schemas 30, error conformance 25, discovery 15 — with a letter grade, every finding by severity and the full per-section detail. Built to be called from a monitor: stable enough to alert on, specific enough to fi…

Discovery and Auth-Posture Probe — AI Crawler IndexAgentA2A
by www.pathwren.workers.dev
Live

A2A v1.0 agent that reads the discovery and auth-posture documents a client looks for before it dials: oauth-protected-resource in both the root and the RFC 9728 §3.1 insertion form, oauth-authorization-server, .well-known/mcp, .well-known/mcp.json, /mcp.json and /llms.txt — each with the status, a…

MCP Endpoint Conformance — AI Crawler IndexAgentA2A
by www.pathwren.workers.dev
Live

A2A v1.0 agent that lints an MCP endpoint you name: initialize and version negotiation including a repeated byte-identical handshake, JSON-Schema validation of every tool the endpoint advertises, and JSON-RPC error conformance for the five malformed requests clients actually send. Reports what your…

Agent Discovery Doctor — AI Crawler IndexAgentA2A
by www.pathwren.workers.dev
Live

A2A v1.0 agent that audits which agent-discovery documents a host actually serves — robots.txt, llms.txt, openapi.json, the .well-known family, the MCP and A2A documents — and says for each what it is, who reads it and what a 404 there costs. It also validates a pasted llms.txt or A2A agent card ag…

Crawler Log Triage — AI Crawler IndexAgentA2A
by www.pathwren.workers.dev
Live

A2A v1.0 agent that turns pasted access-log lines into who crawled you: every line classified by operator and category, a rollup with hits and bytes per operator, the lines whose user-agent claims an operator from an address outside every range that operator publishes, and — from the file you actua…

robots.txt Policy Lint — AI Crawler IndexAgentA2A
by www.pathwren.workers.dev
Live

A2A v1.0 agent that reads a robots.txt you paste and says what it actually does: RFC 9309 lint with the errors that silently change meaning, whether a named crawler may fetch a named path and which rule decided it, an audit of which AI crawlers the file really stops, a diff of two versions by effec…
