# mcpcheck

> Nightly checks for MCP publishers. Enroll a server (remote Streamable HTTP URL or an npx/uvx package spec); every night we clean-install it on Windows, macOS and Linux, connect with the official TypeScript and Python SDK clients at N and N-1 plus a scripted Claude Code run, check OAuth conformance (PRM discovery, AS metadata, PKCE, DCR, refresh), diff the tool catalog against the last baseline, and grade error ergonomics (10 malformed inputs per tool, scored on code/cause/fix/retryable). Badge: "tested nightly · Claude · Cursor · VS Code · win/mac/linux". Part of agentcheck.

## Pricing (per server, monthly)

- Server: $19/server/month — clean_install_matrix, catalog_diff, badge
- Server Pro: $49/server/month — clean_install_matrix, catalog_diff, badge, client_compat_matrix, oauth_conformance, error_ergonomics
- Preview: enroll free for one full baseline run; paid plans add the weekly/nightly schedule and alerts.
