## Quality 73/100 (new)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-03-26; 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

- 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: get_business (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_businesses (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_changes (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 546 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 5 of the 7 days needed

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

- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-11-02 `search_businesses` changed (description, inputSchema) **meaning changed**
  - before: Search verified businesses in the Spotby registry by free text, city and/or category. Returns compact results; use get_business for full details.
  - after: Search businesses in the Spotby registry with natural-language terms (what they do, services, needs) and/or a location. Results are ranked: any term can match, businesses covering more terms come first. Location matches the business address and also the areas the owner says they serve. Each result includes provenance (asserted_by: owner-maintained or imported from open data) and why it matched. Use get_business for full details.
