    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

    What it can reach

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
    Description, as the server wrote it
    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.

    Description, as the server wrote it
    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. For the RENA public-contract ban and environmental penalties, use qc_contractor_check. Provide neq, licence or name.

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.
Reads text others write2
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
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 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

    Matched text

    https://tolca.tonbot.ca/mcp/public: tools/list returned 2 tools to an anonymous client, including qc_contractor_check (write), qc_licence (write)

    What this check looks for

Install

Pinned to version 1.0.1. Values in angle brackets are yours to fill in.

claude mcp add --transport http tolca https://tolca.tonbot.ca/mcp/public

Run in a terminal.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__tolca__qc_contractor_check",
      "mcp__tolca__qc_licence"
    ],
    "deny": []
  }
}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as tolca. Review it before you use it.
