## Quality 100/100 (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 300000)

### 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: 100 (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
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 321 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: 2, about 321 tokens to load them all
- tool set hash: 078c86613588db0c44852469502f5592
- badge: [![protogrid quality](https://protogrid.dev/badge/com.faceabot/deep-search.svg)](https://protogrid.dev/servers/com.faceabot/deep-search)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (2)

- `deep_search`: Search one question at once in sources a normal web search misses: science (arXiv, Crossref), world news in 100+ languages of the last 3 months (GDELT), Internet Archive, GitHub, Wikipedia, and what people say (Bluesky, Mastodon, Lemmy, Hacker News, forums). Results grouped by source, dated, with links.
Use when: you need rich, hard-to-find, sourced information on a subject.
Example: {"query":"agentic commerce paid placement","sources":["science","news"],"lang":"en"}
- `list_deep_sources`: The sources searched by deep_search and what each one covers.
