## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input 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. | none |
| 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 (3)

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

### `check_business_reality`

- 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
Deprecated alias for check_physical_evidence. StreetProof reports accepted physical evidence; it does not determine general business legitimacy. Removal is scheduled for 2026-10-27.
```

### `check_physical_evidence`

- 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
Check whether StreetProof has accepted physical citations associated with a business in a city. This is not a legal-existence, licensing, quality, or address-ownership check. No accepted StreetProof citation matched the request. It never proves absence, closure, inactivity, or that a business is unreal, regardless of coverage tier. Returns an evidence summary, coverage context, and a human-readable citation string to quote when presenting the result.
```

### `city_index`

- 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
Complete snapshot-bound StreetProof PBI records for a city. Follow next_cursor until has_more is false; every page remains fixed to one snapshot. Optionally filter by industry, ranking state, or claim status. Rankings must be interpreted with coverage confidence. Aggregate statistics licensed CC BY 4.0 (attribution required).
```

## Only reads (3)

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

### `compare_presence`

- The name "compare_presence" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Compare the physical presence of multiple businesses in the same city, side by side, ranked by Physical Presence Score.
```

### `get_physical_presence`

- The name "get_physical_presence" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up a business's Physical Presence Score (PPS) and first/last observation dates in a city. Returns the best-matching entity, score components, cohort percentile, and coverage confidence.
```

### `get_pulse`

- The name "get_pulse" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
StreetPulse change events for a city since a date: new public records, newly observed assets, wrapped fleet assets, and stale assets. Closure, rebrand, and vacancy events remain explicitly unavailable until reviewed lifecycle evidence exists.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__streetproof__get_physical_presence",
      "mcp__streetproof__compare_presence",
      "mcp__streetproof__get_pulse"
    ],
    "ask": [
      "mcp__streetproof__city_index",
      "mcp__streetproof__check_physical_evidence",
      "mcp__streetproof__check_business_reality"
    ],
    "deny": []
  }
}
```

| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `3` |

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 3 tools that change things (3 write). Whether a call also works without credentials was not tested: tools are never called.

https://streetproof.com/mcp: tools/list returned 6 tools to an anonymous client, including city_index (write), check_physical_evidence (write), check_business_reality (write)
