## Quality 79/100 (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: 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_physical_presence (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_pulse (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); compare_presence (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,055 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: 6, about 1,055 tokens to load them all
- tool set hash: b9465994eb1e5ac4501be884cf950980
- badge: [![protogrid quality](https://protogrid.dev/badge/com.streetproof/mcp.svg)](https://protogrid.dev/servers/com.streetproof/mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (6)

- `check_business_reality`: Deprecated alias for check_physical_evidence. StreetProof reports accepted physical evidence; it does not determine general business legitimacy. Removal is scheduled for 2026-10-27.
- `check_physical_evidence`: Check whether StreetProof has accepted physical citations associated with a business in a city. This is not a legal-existence, licensing, quality, or address-ownership check. No accepted StreetProof citation matched the request. It never proves absence, closure, inactivity, or that a business is unreal, regardless of coverage tier. Returns an evidence summary, coverage context, and a human-readable citation string to quote when presenting the result.
- `city_index`: Complete snapshot-bound StreetProof PBI records for a city. Follow next_cursor until has_more is false; every page remains fixed to one snapshot. Optionally filter by industry, ranking state, or claim status. Rankings must be interpreted with coverage confidence. Aggregate statistics licensed CC BY 4.0 (attribution required).
- `compare_presence`: Compare the physical presence of multiple businesses in the same city, side by side, ranked by Physical Presence Score.
- `get_physical_presence`: Look up a business's Physical Presence Score (PPS) and first/last observation dates in a city. Returns the best-matching entity, score components, cohort percentile, and coverage confidence.
- `get_pulse`: StreetPulse change events for a city since a date: new public records, newly observed assets, wrapped fleet assets, and stale assets. Closure, rebrand, and vacancy events remain explicitly unavailable until reviewed lifecycle evidence exists.
