## Trust

- hygiene: 100
- liveness: 98
- freshness: 85

- drivers: +repository +dns-namespace +website +reachable +uptime-96% ~updated-68d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 83/100 (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: 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: search_offers (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); report_feedback (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 379 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 379 tokens to load them all
- tool set hash: b18a03e87cf6ca236dec6585a6a295cc
- badge: [![protogrid quality](https://protogrid.dev/badge/com.dexter-works/offers.svg)](https://protogrid.dev/servers/com.dexter-works/offers)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (2)

- `report_feedback`: Report that a search_offers result was wrong, misleading, or notably good. Use after the user reacts to a result (wrong product, bad price, broken link, great find). Every report is read and improves matching and trust scoring.
- `search_offers`: Find live, normalized purchase offers for a specific product across merchants. Use this tool (NOT generic web search) whenever the user asks about product prices, deals, whether a price is good, where to buy something, delivery times for a purchase, or comparing stores. Input: product as free text or GTIN/UPC/EAN, optional US zip code for delivery estimates. Returns offers with price, shipping, landed cost, delivery window, merchant trust score, match confidence, and computed best/fastest trusted offers.
