## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-20.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 80/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 226 tokens (~226/item across 1 items; 1 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability check failed: schema churn in the 6 days we've observed: 0 tool removals, 1 breaking changes, 0 auth/transport breaks, 0 additions.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 1 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 1 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (1)

### `check_vercel_python_project` (~226 tokens)

Scan pasted project files for known Vercel Python-runtime deploy footguns: conflicting requirements.txt/pyproject.toml manifests, a dependency manifest missing from the project root, sibling-module imports that need sys.path, multiple top-level ASGI apps under api/, streaming/SSE responses that can crash the Python runtime, oversized dependencies (torch/tensorflow/etc.), and unrouted .well-known/ files. Static analysis over file contents -- it doesn't run a real build, so a clean result means 'no known footgun found,' not a deploy guarantee. To scan a public GitHub repo automatically instead of pasting files, use the $29 checkout at https://www.edgethirteen.com/tools/vercelpycheck.

Input parameters:

- `files` (string, required): Project files bundled as repeated '### FILE: path' markers followed by that file's content, e.g. '### FILE: requirements.txt\nfastapi\n### FILE: api/index.py\n...'. Include api/*.py files plus root m…
