## Trust

- hygiene: 100
- liveness: 98
- freshness: 85
- provenance: 90
- drivers: +repository +namespace-matches-repo +website +reachable +uptime-96% ~updated-50d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 94/100 (strong)

### protocol: 100 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- pass `protocol.list_ttl`: tool list is cacheable (ttlMs 3600000)

### 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`: 5 of 5 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: web3_search (destructiveHint, idempotentHint, openWorldHint); web3_fetch (destructiveHint, idempotentHint, openWorldHint); web3_grep (destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 424 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`: no 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: 5, about 424 tokens to load them all
- tool set hash: 65a1db2235b55ca8a072ea3f4ce967a9
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.FarseenSh/web3ctx.svg)](https://protogrid.dev/servers/io.github.FarseenSh/web3ctx)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (5)

- `web3_deps`: Dependency closure around a selector. Does not follow calls across projects.
- `web3_fetch`: Full bodies for selectors you already chose, or the next page of a cursor. Does not discover selectors.
- `web3_grep`: Exact lexical match on a known identifier. Does not rank semantically.
- `web3_lookup`: Typed records by id: address, ABI, EIP. Does not search prose or rank.
