- name: io.github.cyanheads/cyanheads-mcp-server
- version: 0.4.4
- connection class: R0 (autonomous)
- trust: 94/100
- quality: 89/100 (good)

**An agent can connect right now, no human step.** Remote endpoint, no authentication, reachable on the last probe.

## Connection (mcpServers)

```json
{
  "mcpServers": {
    "cyanheads-mcp-server": {
      "type": "http",
      "url": "https://cyanheads.caseyjhand.com/mcp"
    }
  }
}
```


## Trust

- hygiene: 100
- liveness: 99
- freshness: 100
- provenance: 80
- drivers: +repository +namespace-matches-repo +reachable +uptime-98% +updated-2d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 89/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### 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: 86 (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
- pass `tools.annotations`: 2 of 2 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: cyanheads_search_catalog (destructiveHint, idempotentHint); cyanheads_describe_entry (destructiveHint, idempotentHint)
- pass `tools.token_cost`: about 919 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`: 4 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`: deps.dev does not know @cyanheads/cyanheads-mcp-server@0.4.4, @cyanheads/cyanheads-mcp-server@0.4.4

- tools: 2, about 919 tokens to load them all
- tool set hash: 93ab0fa56fd9f2e18b286763546c48f4
- tools last changed: 2026-10-19T05:53:18.789Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.cyanheads/cyanheads-mcp-server.svg)](https://protogrid.dev/servers/io.github.cyanheads/cyanheads-mcp-server)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-19 `cyanheads_describe_entry` changed (inputSchema, outputSchema)
- 2026-10-19 `cyanheads_search_catalog` changed (inputSchema, outputSchema)
- 2026-09-30 `cyanheads_describe_entry` changed (description, inputSchema, outputSchema)
  - before: Return the description and install snippets for a named tool or server. For tools: the description and the server it belongs to. For servers: local (stdio, via npx) install snippets for every published server, plus remote (HTTP) connection snippets when a hosted endpoint exists — for every supported client, or one client via the client parameter.
  - after: Return the description and install snippets for a named tool or server. For tools: the description, owning server, and connection metadata. For either kind: local (stdio, via npx) install snippets for every published server, plus remote (HTTP) connection snippets when a hosted endpoint exists — for every supported client, or one client via the client parameter.
- 2026-09-30 `cyanheads_search_catalog` changed (inputSchema, outputSchema)

- npm @cyanheads/cyanheads-mcp-server@0.4.4

## Tools (2)

- `cyanheads_describe_entry`: Return the description and install snippets for a named tool or server. For tools: the description, owning server, and connection metadata. For either kind: local (stdio, via npx) install snippets for every published server, plus remote (HTTP) connection snippets when a hosted endpoint exists — for every supported client, or one client via the client parameter.
- `cyanheads_search_catalog`: Search fleet tools and servers by natural-language description. Returns ranked matches with brief summaries and the server each tool belongs to. Use scope "servers" to find which server handles a workflow; use the default scope "tools" to find specific tools.
