### Description (declared)

# mcp-trust-check

One GitHub Action that runs the full MCP trust & safety trilogy — [`mcp-doctor`](https://github.com/vishalhabib99/mcp-doctor), [`mcp-fuzz`](https://github.com/vishalhabib99/mcp-fuzz), [`mcp-reality-check`](https://github.com/vishalhabib99/mcp-reality-check) — against an [MCP](https://modelcontextprotocol.io) server and posts one combined score, instead of three separate installs and three separate reports. Also a Python package (`pip install mcp-trust-check`) doing the same job for a live agent session instead of a CI run — see [Live session wrapper](#live-session-wrapper) below.

Each of the three tools already works standalone and does something the other two structurally can't:

- **mcp-doctor** reads the server's source and checks spec conformance/security/documentation — no server execution needed.
- **mcp-fuzz** actually launches the server and calls every tool with schema-derived inputs, checking crash resilience, latency, response size, and (opt-in) concurrency and resource-lifecycle correctness.
- **mcp-reality-check** also launches the server, but checks whether a tool's *successful* response is actually trustworthy — no disguised refusals, no empty content, no output that quietly ignores its own schema.

None of them use an LLM judge anywhere — every check here is deterministic and reproducible, same as the tools it wraps.

## Demo

35 seconds, live run against the official MCP reference server — real output, no cherry-picking: 86%/B code quality, 100%/A crash resilience, 100%/A output fidelity, 95%/A combined.

## Use

Static-only — zero extra config, works on any checked-out repo:

```yaml
- uses: actions/checkout@v4
- uses: vishalhabib99/mcp-trust-check@v1
  with:
    path: .
```

Full trilogy — also add `run` with the command that actually starts your server over stdio:

```yaml
- uses: actions/checkout@v4
- uses: vishalhabib99/mcp-trust-check@v1
  with:
    path: .
    run…
