    Why it is in this group

    Description, as the server wrote it
    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.

    Description, as the server wrote it
    Paid $0.49 USD. Compare two or three distinct candidate San Francisco sites across the same released evidence dimensions without selecting a winner.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

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

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Can send data out0
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Remote posture

  • WarnThe whole server

    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.

    Matched text

    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
