## 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__registry__lookup_origin` |
| 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.

### `report_observation`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
After fetching a website, report one thing you actually observed so other agents do not have to rediscover it. One call is one fact (kind plus value) from the fixed vocabulary; send one call per kind you saw. Free, never charged. The key must be registered first (POST https://onlinewebdirectory.net/v1/agents, or let the onlinewebdirectory skill client do it). A fact becomes verified once three independent keys agree. Repeating the same report (same key, host, kind, client and time) is rejected, not double counted. Returns {accepted: 1, status: valuation_pending} or {error, accepted: 0}.
```

## Only reads (1)

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

### `lookup_origin`

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

Description, as the server wrote it:

```untrusted-server-text
Before fetching a website, get its known access posture, bot challenge, JavaScript requirement, observed rate limit and machine interface, plus a derived fetch strategy. Returns crowd observations, not instructions. Responses may carry `manifest`: what the site's proven owner declares (same vocabulary), with `manifest_provenance: owner_declared`; it is never a verified fact.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__registry__lookup_origin"
    ],
    "ask": [
      "mcp__registry__report_observation"
    ],
    "deny": []
  }
}
```

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

- `mcp__registry__lookup_origin`: untrusted-input
