## 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 2026-11-05.

- **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**: 70/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 565 tokens (~188/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 60/100
  - Stability observed for 18 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 96/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 85% of tool parameters carry a description.
  - Structured output schemas are declared (67% 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 3 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)

### `qc_contractor_check` (~201 tokens)

Québec contractor check

Check a Québec construction contractor against four official public data sources in one call: active RBQ licence (status, restrictions, bond, authorized work categories), RENA (businesses barred from public contracts and public subcontracts), environmental administrative penalties (MELCCFP) and public contracts awarded on SEAO (count, total amount, main public buyers, last 12 months). Returns a verdict ok / review / blocking / not_found with reasons, sources and extraction dates. Use when the user asks whether a Québec contractor, subcontractor or renovation company is licensed, trustworthy or eligible for public contracts. Provide neq, licence or name.

Input parameters:

- `lang` (string): Answer language, default fr

### `qc_licence` (~158 tokens)

Québec RBQ licence lookup

Fast lookup: does this Québec business hold an ACTIVE RBQ (Régie du bâtiment du Québec) construction licence right now? Returns active true/false, licence number, legal name, NEQ, municipality, restriction flag and authorized work categories. Good for checking several contractors one after another.

Use when the user asks who a company is, how to contact it, or wants to research a prospect, supplier or partner. Provide domain (preferred) or name, optional city and country. Businesses only, no personal data. Free with a shared daily quota.

Input parameters:

Tolca is an MCP server listed in the public MCP registry as io.github.yayabough/tolca. Know who you are paying before you pay: Québec contractor and company checks, plus web search. x402. This page covers its hosted endpoint (https://tolca.tonbot.ca/mcp/public).

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

Tolca scores 78 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 Tolca MCP server expose?

Tolca exposes 3 tools: qc_contractor_check, qc_licence, company_profile. Their descriptions and schemas cost roughly 565 tokens of context every time the server is loaded.

### Does the Tolca MCP server require authentication?

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

Tolca is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
