## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-21.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 81/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 364 tokens (~121/item across 3 items; 3 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (3)

### `search_address_permits` (~114 tokens)

Search permits for a public address

Look up the public PropertyLabs permit history for a specific civic address in a specific city. Use this for address-level construction history and activity. This follows the same public field boundary as PropertyLabs address pages and does not return applicant names, contractor names or permit numbers.

Input parameters:

- `address` (string, required): Specific civic address, for example 8882 170 Street NW.
- `city` (string, required): Required PropertyLabs city slug, for example 'calgary', 'edmonton', 'toronto' or 'vancouver'.

### `get_public_permit` (~101 tokens)

Get a public PropertyLabs permit record

Retrieve a permit using the numeric PropertyLabs canonical permit ID and city slug. Use this for a permit already referenced by a public PropertyLabs /permit/{city}/{id} URL. Returns only fields allowed on the public permit page; applicant and contractor identities remain gated.

Input parameters:

- `canonical_id` (string, required): Numeric PropertyLabs canonical permit ID from a public PropertyLabs permit URL.
- `city` (string, required): Required PropertyLabs city slug from the public permit URL.

### `search_company_activity` (~104 tokens)

Get a public company activity snapshot

Get an aggregate, city-scoped sample of permit activity matching a developer, applicant, builder or contractor name. Only applicant/developer/contractor party-field matches are counted. Anonymous results are aggregate only and never return company-matched project addresses, permit numbers, coordinates or raw records.

Input parameters:

- `city` (string, required): Required PropertyLabs city slug. Company activity is never queried across the full archive anonymously.
- `company` (string, required): Developer, applicant, builder or contractor name.

## Common questions

### What is the PropertyLabs MCP server?

PropertyLabs is an MCP server listed in the public MCP registry as io.github.AlgoFalgo/propertylabs. Public building permits, property assessments, parcels and development intelligence. This page covers its hosted endpoint (https://propertylabs.org/mcp).

### Is the PropertyLabs MCP server safe to use?

PropertyLabs scores 86 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the PropertyLabs MCP server expose?

PropertyLabs exposes 3 tools: search_address_permits, get_public_permit, search_company_activity. Their descriptions and schemas cost roughly 319 tokens of context every time the server is loaded.

### Does the PropertyLabs MCP server require authentication?

No. We connected to PropertyLabs without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the PropertyLabs MCP server still maintained?

PropertyLabs is still listed as active in the MCP registry. We last reached this channel on 21 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
