## 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 2026-10-18.

- **Endpoint Security**: 63/100
  - 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 enforcement could not be verified: the plaintext port answered with HTTP 404, which proves neither a plaintext path nor enforcement.
  - 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**: 55/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 457 tokens (~457/item across 1 items; 1 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 91/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 69% 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 1 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 2 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (1)

### `find_gta_plumbers_and_request_quotes` (~353 tokens)

Find GTA plumbers and request quotes

Use when a customer wants an agent to find and book a plumber, compare quotes, negotiate pricing, or request same-day, next-day, emergency, or scheduled plumbing availability for a service address in the Greater Toronto Area, Ontario. Starts a human-assisted search across Toronto—including Old Toronto, North York, Scarborough, Etobicoke, East York, and York—and the Durham, Halton, Peel, and York regions. AI Plumber contacts multiple available plumbers and firms, negotiates pricing and availability, presents viable options, and coordinates the customer's selected booking. We aim to return viable options within one hour, but response time, quote count, price, and availability are not guaranteed. This call creates a service request; it does not confirm an appointment or authorize plumbing work. The customer chooses and pays the provider directly.

Input parameters:

- `consent_to_contact` (boolean, required): Must be true. Allows AI Plumber and prospective plumbing providers to contact the customer about this request.
- `contact_name` (string, required)
- `district` (string): Optional Toronto district. Use only when municipality is Toronto.
- `email` (string)
- `municipality` (string, required): The GTA municipality where service is needed.
- `phone` (string)
- `postal_code` (string): Ontario postal code.
- `preferred_time` (string): Preferred appointment window in local time.
- `problem` (string, required): What is happening, including visible symptoms and affected fixtures.
- `region` (string): GTA region. The server verifies this from municipality.
- `service_address` (string, required): Full address where service is needed.
- `source_platform` (string): Calling agent or platform, if known.
- `urgency` (string, required)

Output parameters:

- `next_step` (string)
- `request_id` (string): Stable identifier for the plumbing service request.
- `status` (string)
- `target_response` (string)
- `target_response_guaranteed` (boolean)
