## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-20.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 406, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 82/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 475 tokens (~79/item across 6 items; 2 tools + 4 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 50/100
  - Stability observed for 15 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.
  - An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

### How do I install the Locus MCP server?

Locus is a hosted endpoint at https://api.locus.report/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## MCP tools (2)

### `locus_search_tools` (~167 tokens)

Search Locus tool catalog

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. Install agent skill: npx @velinussage/locus-agent-skill add.

Input parameters:

- `limit` (integer): Maximum matching catalog entries to return.
- `query` (string): Keyword query over tool name, title, description, and tags.
- `tags` (array): Optional tags that every result must include.
- `tier` (string): Filter by free or paid tools.

### `locus_execute` (~189 tokens)

Execute a Locus catalog tool

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.

Input parameters:

- `args` (object): Alias of arguments.
- `arguments` (object): Arguments for the selected catalog tool (the tool's own inputSchema from locus_search_tools).
- `input` (object): Alias of arguments.
- `name` (string): Canonical Locus catalog tool name. Paid tools keep their hyphenated REST slugs.
- `tool` (string): Alias of name.

## Common questions

### What is the Locus MCP server?

Locus is an MCP server listed in the public MCP registry as io.github.velinussage/locus. Official US-address public records: zoning, flood, parcel, permits, taxes. Free look, x402 paid. This page covers its hosted endpoint (https://api.locus.report/mcp).

### Is the Locus MCP server safe to use?

Locus scores 75 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Locus MCP server expose?

Locus exposes 2 tools: locus_search_tools, locus_execute. Their descriptions and schemas cost roughly 356 tokens of context every time the server is loaded.

### Does the Locus MCP server require authentication?

No. We connected to Locus without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Locus MCP server still maintained?

Locus is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
