Security profile

Claimed and verified servers get a weekly static scan that shows what the code can reach: external services, environment variables, shell commands, agent configuration folders, plus any dependencies with known advisories. Claim this listing to get one. How the security profile works

Documented tools (5)

From project documentation. A server handshake does not verify each tool’s description or behavior.

Capability-driven

tests adapt to what the server declares. If it says it supports tools, tool tests become required. No false failures for features the server doesn't claim.

CI-ready

--strict mode exits with code 1 on required test failures. Drop it into any pipeline.

mcp_compliance_explain

Explain what a specific test ID checks and why it matters.

mcp_compliance_test

Run the full 88-test suite against a URL or stdio command. Supports auth, custom headers, env vars, timeout, retries, and category/test filtering. Returns grade, score, and detailed results.

Spec-referenced

every test links to the exact section of the MCP specification it validates. No ambiguity about what's being tested or why.

Tool change history

Compared across complete checks of the same configuration. Tools were listed, not invoked. Input-schema changes are not measured here.
