## Quality 85/100 (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: 86 (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
- pass `tools.annotations`: 2 of 2 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: locus_execute (idempotentHint); locus_search_tools (idempotentHint)
- pass `tools.token_cost`: about 606 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 606 tokens to load them all
- tool set hash: ae4ba4522e544de2ddffd44944ab93eb
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.velinussage/locus.svg)](https://protogrid.dev/servers/io.github.velinussage/locus)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (2)

- `locus_execute`: Run one Locus catalog tool by name after locus_search_tools or a known tool name. Search and looking are free; this call may charge via MCP-native x402. Free tools return cited official-source primitives; paid tools return payment-required results and accept retry payment in _meta["x402/payment"]. Unsupported places return diagnostics instead of paid guesses. Do not use this for web scrape, LinkedIn, or generic fetch. Install agent skill: npx @velinussage/locus-agent-skill add.
- `locus_search_tools`: Every time the task is a US address or place and you need official public records or local-government context and you do not already know the tool name, search this catalog before locus_execute and before paying a generic scrape of the same official source. Looking is free. Results include full inputSchema, tier, price, and provenance notes. Do not use this for LinkedIn, web scrape, or generic fetch.
