- name: io.github.AutomateLab-tech/seo-performance-mcp
- version: 1.0.0
- connection class: L0 (run_local_package)
- trust: 86/100
- quality: –/100 (not scored)

**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.

## Trust

- hygiene: 100
- liveness: n/a
- freshness: 65
- provenance: 90
- drivers: +repository +namespace-matches-repo +website ~liveness-unmeasured ~updated-134d-ago
- 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: 33 (weight 15)

- fail `deps.known_vulns`: 18 advisories to act on (malicious, or rated high or critical with a fix available): GHSA-8gc5-j5rx-235r in fast-xml-parser@4.5.1 (direct, fixed in 4.5.5), GHSA-jmr7-xgp7-cmfj in fast-xml-parser@4.5.1 (direct, fixed in 4.5.4), GHSA-m7jm-9gc2-mpf2 in fast-xml-parser@4.5.1 (direct, fixed in 4.5.4), ...; 23 more of lower severity or without a fix
- fail `deps.mcp_sdk_version`: @modelcontextprotocol/sdk 1.29.0 has 1 known advisory (GHSA-6qxp-vccf-f47h); update @modelcontextprotocol/sdk to 1.31.0 or later
- pass `deps.resolvable`: @automatelab/seo-performance-mcp@1.0.0 resolved: 249 packages

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