The real catalog of tools for AI agents

Experimental MCP server for current empirical verification of explicit public HTTPS endpoint claims.

MCP conformance test harness. JSON-RPC, OAuth 2.1 PKCE, schemas, smoke, annotations. CLI + lib.

Live-payload conformance probes with signed receipts: ABSENT/EMPTY/PARTIAL/COMPLETE/BROKEN.

Diagnoses whether an MCP server is reachable, by live HTTP probe.

solve_need: one call returns the best of 46,000+ MCP tools, with live measured reliability.

Inspect and score any MCP server 0-100 on publishability, schema and protocol before publish.

Caller-specific static MCP capability fit evidence. No live probing; caller owns the decision.

Validate JSON, YAML, XML and CSV with exact line/column errors and silent-corruption warnings.

Spec-driven dev workflow MCP: start_* orchestration, memory, GitNexus, quality gates.

Find MCP servers and check whether they actually respond, via live handshake probes.

Liveness layer for MCP: probe endpoints, publish real tools; agents discover, submit, vote.

Email verification for AI agents: send, hold or kill with the reason. Signup and credits by API.

Audits MCP servers for Claude Code mcp_tool hook readiness: idempotency, latency, side-effects.

Run network tests (ping, traceroute, DNS) from probes worldwide

Hardware probe for performance diagnostics, thermal monitoring, and LLM optimization.

Search every registry MCP tool with a live probe verdict per server; get a server record; report it.

Check an x402-paid API endpoint's trust score before paying it - live-probed, not self-reported.

Check what a paid x402 endpoint or MCP server delivered, from probes anyone can repeat.

MCP tools for x402 readiness, paid-path probes, launch packs, and trust receipts.

Health and token cost of every remote MCP registry server, probed daily. Look up, search, or probe.
