## What eczid-mcp-verifier does, in the publisher's words

Check the public ECZ-ID Resolver posture of an MCP server, agent, API or business from any MCP-capable agent host. Local-first, read-only, deterministic. Never writes truth, never scores, never uploads source.

No account, no sign-in, no licence key, no trial and no paywall. Every capability described below works in full as soon as you install it, in whatever host you run it in, for free.

This plugin is open source under the MIT licence (the ECZ-ID Verifier npm package it launches carries its own licence): https://github.com/Ecocitizenz/eczid-agent-plugins

- Skill ecz-id-verify teaches the agent to use the read-only ECZ-ID Verifier tools correctly and to report ResultStates and ReasonCodes without turning them into a score.
- MCP server ecz-id-verifier: @ecocitizenz/ecz-id-mcp-verifier@0.9.0 over stdio, three read-only tools (ecz_check_target, ecz_explain_result, ecz_recheck_resolver). Launched by the host with npx; nothing is installed globally.
