## Trust

- hygiene: 100
- liveness: 100
- freshness: 65
- provenance: 80
- drivers: +repository +namespace-matches-repo +reachable +uptime-99% ~updated-96d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 76/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### 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: 64 (weight 30)

- pass `tools.descriptions`: every tool has a description
- warn `tools.description_length`: 1 tools have descriptions over 1,024 characters, which crowds the context
- 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: verify_capability (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); find_best_merchant (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_offerings (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 753 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 753 tokens to load them all
- tool set hash: e9d654180550258e611d9b263bee2746
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.primoliquors/beacon.svg)](https://protogrid.dev/servers/io.github.primoliquors/beacon)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (5)

- `find_best_merchant`: 
    Rank merchants that can actually fulfill a purchase need, by honest signals only.

    Args:
        category: product category, e.g. "vodka".
        ship_to: ISO region the order must ship to, e.g. "US-FL".
        require_age_gate: only return merchants that enforce 21+.
        limit: max results.
        optimize_for: what matters to the BUYER -- "trust" (default), "price"
            (lowest matched price), or "speed" (same-day, then next-day
            fulfillment). Ties always break by earned trust.
        product_type/dest_state/channel: pass all three (e.g. "spirits", "FL",
            "ship"|"local_delivery") for STRICT COMPLIANCE mode -- only merchants
            with attested age-gate + attested license + a legal jurisdiction
            path are returned, each with its compliance verdict.
    Every result carries ships_to states (match them against where the buyer
    lives), best_price, and the evidence behind the record. Paid placement never
    affects any ranking (ranking_basis states the basis actually used).
    
- `get_merchant_view`: Full agent view of one merchant: record + offerings + capabilities + evidence.
- `index_stats`: Graph coverage stats: counts of registry entries, merchants, offerings, capabilities.
- `search_offerings`: Find offerings (products) matching a category, joined to merchant + capabilities.
- `verify_capability`: Verify a merchant capability with evidence, e.g. age_gate_21 or ships_to_US-FL.
