## Quality 83/100 (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: 93 (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
- 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 1,499 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 75 (weight 15)

- warn `stability.changes`: 6 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 1,499 tokens to load them all
- tool set hash: f448c21c44ce025df5a7b0f03c98f4e9

  - before: Resolve one physical U.S. facility and return a bounded, source-reconciled environmental regulatory evidence report covering core air, water, hazardous-waste, and drinking-water programs plus inspections, reported violations, formal enforcement, penalties, freshness, source gaps, and conflicts. Use when an agent needs evidence about one specific facility and wrong-site matching or missing-source inference would be costly; do not use for company-wide research, raw EPA record retrieval, legal advice, or a clean/compliant verdict. Provide frsId or programId when known; otherwise provide name with enough location context to resolve exactly one site. This is a $1.00 USD MPP operation when commerce is active in a released state. California and Texas are currently released for paid full-compliance evidence; Florida is in development and remains unreleased. Identity and state eligibility are resolved before payment, ambiguous/unresolved/unreleased requests are not charged, and the call does not alter regulatory records. A fresh authorized invocation can charge again, while a settled delivery retry should reuse the identical request with the same payment credential to recover without a second settlement.

- 2026-09-27 `facilityproof.check_permit_identity` added
  - Resolve one physical U.S. facility and return authoritative FRS environmental program/permit identifiers plus qualified jurisdiction and source-system provenance before deeper compliance research. This is a $0.10 USD MPP operation when commerce is active. It is currently jurisdiction-ready in 40 states. Ambiguous identity, medium-confidence identity, linked-record conflicts, missing routed program identity, and states with unresolved Tribal/federal carve-outs are rejected before payment. The result does not determine compliance, permit status, violations, enforcement, or penalties.
