> An MCP server to query Hydrolix

- name: io.github.hydrolix/mcp-hydrolix
- version: 0.2.3
- connection class: L0 (run_local_package)
- trust: 74/100
- quality: –/100 (not scored)
- owner: not claimed
- descriptor: https://api.protogrid.dev/v1/servers/io.github.hydrolix%2Fmcp-hydrolix
- tools: https://api.protogrid.dev/v1/servers/io.github.hydrolix%2Fmcp-hydrolix/tools

**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": {
    "mcp-hydrolix": {
      "command": "uvx",
      "args": [
        "mcp-hydrolix==0.2.3"
      ],
      "env": {
        "HYDROLIX_HOST": "${HYDROLIX_HOST}",
        "HYDROLIX_TOKEN": "${HYDROLIX_TOKEN}",
        "HYDROLIX_PASSWORD": "${HYDROLIX_PASSWORD}"
      }
    }
  }
}
```

Placeholders to fill: `${HYDROLIX_TOKEN}`, `${HYDROLIX_PASSWORD}`.

## Trust

- hygiene: 100
- liveness: n/a
- freshness: 45
- provenance: 75
- drivers: +repository +namespace-matches-repo -thin-description ~liveness-unmeasured -stale-195d
- 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: 67 (weight 15)

- fail `deps.known_vulns`: 4 advisories to act on (malicious, or rated high or critical with a fix available): GHSA-9v7f-9g4p-ffgj in pyjwt@2.12.1 (direct, fixed in 2.14.0), GHSA-ffc3-869f-jxw9 in pyjwt@2.12.1 (direct, fixed in 2.14.0), GHSA-p4g4-x82p-q773 in pyjwt@2.12.1 (direct, fixed in 2.14.0), ...; 12 more of lower severity or without a fix
- pass `deps.mcp_sdk_version`: mcp 1.30.0, no known advisory
- pass `deps.resolvable`: mcp-hydrolix@0.2.3 resolved: 78 packages

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