## Exfil surface

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

| 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__cartographer__find_apify_actors` `mcp__cartographer__find_x402_endpoints` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__cartographer__x402_endpoint_card` |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `x402_endpoint_card`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Trust card for one x402 endpoint URL: 7-day uptime from our probes, latency, last success, price, and the seller's on-chain USDC payers over 30 days. Not charged for unknown URLs.
```

## Only reads (3)

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

### `cartographer_status`

- The name "cartographer_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Free: price, network and data freshness of this server's paid tools.
```

### `find_apify_actors`

- The name "find_apify_actors" says "find": a word for reading.
- Tag untrusted-input: The description's first sentence says "post": it reads posts, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Picks Apify Store actors for a scraping or automation task such as 'instagram posts' or 'google maps places'. Returns up to 10 actors ranked by text match, 30-day users and run success rate, with per-event price and an x402 run URL. Not charged when nothing matches.
```

### `find_x402_endpoints`

- The name "find_x402_endpoints" says "find": a word for reading.
- Tag untrusted-input: The description's first sentence says "web": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Ranks live x402 endpoints for a task such as 'web search', 'token price' or 'pdf to text'. Returns up to 10 endpoints ranked by text match, 7-day liveness probes and on-chain USDC payer counts. Not charged when nothing matches.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__cartographer__find_x402_endpoints",
      "mcp__cartographer__find_apify_actors",
      "mcp__cartographer__cartographer_status"
    ],
    "ask": [
      "mcp__cartographer__x402_endpoint_card"
    ],
    "deny": []
  }
}
```

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

- `mcp__cartographer__find_x402_endpoints`: untrusted-input
- `mcp__cartographer__x402_endpoint_card`: outbound
- `mcp__cartographer__find_apify_actors`: untrusted-input
