## Connection (mcpServers)

```json
{
  "mcpServers": {
    "skill-audit-mcp": {
      "type": "http",
      "url": "https://eltociear-skill-audit.hf.space/mcp"
    }

```


## Trust

- hygiene: 95
- liveness: 100
- freshness: 100
- provenance: 80
- drivers: +repository +namespace-matches-repo +reachable +uptime-100% +updated-20d-ago -unpinned-packages(1)
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### 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: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: paid_catalogue (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); earthquakes (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); country_indicator (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,216 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: 2 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

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

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 11, about 1,216 tokens to load them all
- tool set hash: 555554fdf8f4b6750e89efe98e6b7a9a
- tools last changed: 2026-09-30T07:23:52.039Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.eltociear/skill-audit-mcp.svg)](https://protogrid.dev/servers/io.github.eltociear/skill-audit-mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-09-30 `audit_skill_url` changed (description)
  - before: Fetch a URL and scan what it serves for malicious behaviour. 17 attack patterns / 59 regex signatures across 4 severity levels — credential exfiltration, download-and-execute, prompt injection, command execution, seed-phrase harvesting and more.
  - after: Fetch a URL and scan what it serves for malicious behaviour. 17 attack patterns / 65 regex signatures across 4 severity levels — credential exfiltration, download-and-execute, prompt injection, command execution, seed-phrase harvesting and more.
- 2026-09-30 `audit_skill_text` changed (description)
  - before: Scan text — an agent skill, MCP server source, or plugin — for malicious behaviour before loading it. 17 attack patterns / 59 regex signatures across 4 severity levels — credential exfiltration, download-and-execute, prompt injection, command execution, seed-phrase harvesting and more.
  - after: Scan text — an agent skill, MCP server source, or plugin — for malicious behaviour before loading it. 17 attack patterns / 65 regex signatures across 4 severity levels — credential exfiltration, download-and-execute, prompt injection, command execution, seed-phrase harvesting and more.

## Tools (11)

- `air_quality`: Current air quality for a place: PM2.5, PM10, ozone, NO2, SO2, CO and dust, plus the US and European AQI and the US AQI band ('Good', 'Unhealthy'). Takes a place name — no coordinates needed. (Free. This server also sells a paid API — call `paid_catalogue` for the routes and prices; x402 over USDC on Base, no signup.)
- `audit_skill_text`: Scan text — an agent skill, MCP server source, or plugin — for malicious behaviour before loading it. 17 attack patterns / 65 regex signatures across 4 severity levels — credential exfiltration, download-and-execute, prompt injection, command execution, seed-phrase harvesting and more.
- `audit_skill_url`: Fetch a URL and scan what it serves for malicious behaviour. 17 attack patterns / 65 regex signatures across 4 severity levels — credential exfiltration, download-and-execute, prompt injection, command execution, seed-phrase harvesting and more.
- `country_indicator`: World Bank time series for a country: gdp, gdp_per_capita, population, inflation, unemployment, life_expectancy, co2_per_capita or internet_users. (Free. This server also sells a paid API — call `paid_catalogue` for the routes and prices; x402 over USDC on Base, no signup.)
- `earthquakes`: Recent earthquakes from the USGS feed — worldwide, or within a radius of a named place. Returns magnitude, depth, tsunami flag and felt reports. (Free. This server also sells a paid API — call `paid_catalogue` for the routes and prices; x402 over USDC on Base, no signup.)
- `elevation`: Ground elevation in metres for a place name. (Free. This server also sells a paid API — call `paid_catalogue` for the routes and prices; x402 over USDC on Base, no signup.)
- `geocode`: Resolve a place name to coordinates, country, admin region, timezone, elevation and population. (Free. This server also sells a paid API — call `paid_catalogue` for the routes and prices; x402 over USDC on Base, no signup.)
- `paid_catalogue`: List the paid API routes this same server offers, with prices and which ones need no input. The MCP tools here are free and general-purpose; the paid routes are specialised (on-chain token safety, live DEX prices, wallet intel, supply-chain scans). Payment is x402 over USDC on Base — no account or API key. Takes no arguments.
- `public_holidays`: Public holidays for a country and year, with local names and a past/upcoming flag. (Free. This server also sells a paid API — call `paid_catalogue` for the routes and prices; x402 over USDC on Base, no signup.)
