- connection class: L0 (run_local_package)

**Runs on your machine: something must execute the package.** Only local packages are published (npm, PyPI, OCI, …). The registry never executes them, so tools are unknown until you run it.

## Connection (mcpServers)

```json
{
  "mcpServers": {
    "dead-letter": {
      "command": "uvx",
      "args": [
        "--python",
        "3.12",
        "--from",
        "dead-letter[mcp]==0.4.8",
        "dead-letter==0.4.8",
        "dead-letter-mcp"
      ]
    }
  }
}
```


## Trust

- hygiene: 95
- liveness: n/a
- freshness: 100
- provenance: 80
- drivers: +repository +namespace-matches-repo ~liveness-unmeasured +updated-11d-ago -unpinned-packages(1)
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality –/100 (not scored)

Not scored: fewer than three checks apply, usually because no remote answered a credential-free probe or the server is a local package.

### protocol: n/a (weight 25)

- n/a `protocol.modern`, `protocol.stateless`, `protocol.transport`, `protocol.list_ttl`: no remote answered a protocol handshake (not probed yet, unreachable, or local-only)

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: n/a (weight 30)

- n/a `tools.descriptions`, `tools.description_length`, `tools.schemas`, `tools.annotations`, `tools.directory_hints`, `tools.token_cost`, `tools.api_dump`: tool list unknown (behind auth, not probed, or empty)

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool list unknown

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: deps.dev does not know dead-letter@0.4.8

- tools: unknown
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.BigCactusLabs/dead-letter.svg)](https://protogrid.dev/servers/io.github.BigCactusLabs/dead-letter)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.
