## 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__localproof__localproof_build_development_due_diligence` `mcp__localproof__localproof_build_property_intelligence_pack` `mcp__localproof__localproof_check_code_enforcement` `mcp__localproof__localproof_check_parcel_context` `mcp__localproof__localproof_check_permit_routing` `mcp__localproof__localproof_check_permits` `mcp__localproof__localproof_check_planning_activity` `mcp__localproof__localproof_check_property_changes` `mcp__localproof__localproof_check_zoning_context` `mcp__localproof__localproof_compare_sites` `mcp__localproof__localproof_get_coverage` `mcp__localproof__localproof_get_source_catalog` `mcp__localproof__localproof_get_source_health` `mcp__localproof__localproof_resolve_jurisdiction` |

## Findings

- **warn** Annotations that disagree with the tool in `localproof.compare_sites` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "localproof.compare_sites" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":true}; The name "localproof.compare_sites" says "compare": a word for reading.

## Changes things (10)

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

### `localproof.build_development_due_diligence`

- Nothing in its name or description says what it does, so it is counted as a write.
- 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
Paid $2.95 USD. Build the deepest released San Francisco development evidence package with cross-source chronology, attention items, completeness, source gaps, provenance, and repeat-poll guidance through check_property_changes. Use this for development due diligence; use build_property_intelligence_pack for a lighter current snapshot. Unsupported or held jurisdictions fail before payment.
```

### `localproof.build_property_intelligence_pack`

- Nothing in its name or description says what it does, so it is counted as a write.
- 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
Paid $0.25 USD. Build the broad released multi-source property package with completeness, source gaps, provenance, and repeat-poll guidance through check_property_changes.

```

### `localproof.check_code_enforcement`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

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

```

### `localproof.check_zoning_context`

```

## Only reads (4)

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

### `localproof.get_coverage`

- The name "localproof.get_coverage" says "get": a word for reading.
- 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
Free. Return released and held jurisdiction and operation coverage without querying property records. Use this to plan routing; use resolve_jurisdiction when you have a specific address.
```

### `localproof.get_source_catalog`

- The name "localproof.get_source_catalog" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

- 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

- The name "localproof.resolve_jurisdiction" says "resolve": a word for reading.
- 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
Free. Resolve one address or place to a supported LocalProof jurisdiction and coverage state before deeper research. Use this when jurisdiction support is unknown; use get_coverage to inspect published coverage without resolving a property. Held or unsupported jurisdictions fail closed before paid work.
```

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 10 tools that change things (10 write). Whether a call also works without credentials was not tested: tools are never called.

https://localproof.davisvillelabs.com/mcp: tools/list returned 14 tools to an anonymous client, including localproof.check_property_changes (write), localproof.check_permits (write), localproof.check_permit_routing (write), localproof.check_parcel_context (write), localproof.check_planning_activity (write) and 5 more
