## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__locus__locus_execute` `mcp__locus__locus_search_tools` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `locus_execute`

- The name "locus_execute" says "execute": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Only reads (1)

Looks things up and changes nothing. Claude Code: allow.

### `locus_search_tools`

- The name "locus_search_tools" says "search": a word for reading.
- Tag untrusted-input: The description's first sentence says "scrape": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `locus`:

```json
{
  "permissions": {
    "allow": [
      "mcp__locus__locus_search_tools"
    ],
    "ask": [
      "mcp__locus__locus_execute"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__locus__locus_search_tools`: untrusted-input
- `mcp__locus__locus_execute`: untrusted-input
