## Trust

- hygiene: 100
- liveness: 99
- freshness: 100

- drivers: +repository +dns-namespace +website +reachable +uptime-97% +updated-23d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 85/100 (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: 75 (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: get_cast_link (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 369 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump
- pass `tools.hidden_text`: no hidden text in tool names, descriptions, schemas or annotations

### stability: 100 (weight 15)

- pass `stability.changes`: 5 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name
- pass `stability.new_links`: no tool change named a new site

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

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

- tools: 1, about 369 tokens to load them all
- tool set hash: 0ebbca7630ad23667bcee76d1da23267
- tools last changed: 2026-10-31T03:39:51.130Z
- badge: [![protogrid quality](https://protogrid.dev/badge/xyz.forkcaster/mcp.svg)](https://protogrid.dev/servers/xyz.forkcaster/mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

  - before: Resolve a Farcaster cast — identified by username/fid + short hash, or by its full 40-hex hash — and return the URL that opens it in a target Farcaster client app (or all supported apps). Also returns the author's signed-contract status; URLs are returned regardless of signed state.
  - after: Resolve a Farcaster cast — identified by username/fid + short hash, or by its full 40-hex hash — and return the URL that opens it in a target Farcaster client app (or all supported apps). Also returns the author's signed-contract status; URLs are returned regardless of signed state. Link-only clients are gated: they answer client_ineligible when the resolved cast carries no external link.
