Whose server it is
  • Registry namepro.wrench/vehicle-checkverified in the MCP registry

The registry name sits under wrench.pro. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-20 the server answered initialize and tools/list without a sign-in. First answer in 142 ms.

  • Whether its tools do the product's job has not been judged yet.
  • Checked on 5 of the 7 days it takes to judge reliability.

Once connected

  • For "Review known issues and recalls before negotiating a repair", the likely first call is resolve_vehicle.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

None of the five warning signs in these definitions.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

  • resolve_vehicle

    Use FIRST whenever the user names a vehicle ('2017 Ford Escape', "'17 F150", 'my Honda Civic') unless you already have exact slugs from a previous call. Pass the user's words in `query`. Returns kind=exact (use the returned slugs)…

  • get_vehicle_summary

    Use for broad questions about a vehicle ('should I buy it', 'what goes wrong with it', 'tell me about it'). Requires exact slugs from resolve_vehicle. Pass mileage when the user mentioned their odometer to get due-now service items, and…

  • get_recalls

    Use when the user asks specifically about recalls or safety campaigns. Requires exact slugs from resolve_vehicle. Always tell the user to confirm against their own VIN at nhtsa.gov/recalls before acting on safety issues.

  • get_known_issues

    Use when the user asks what commonly goes wrong, about reliability, or about a specific symptom. mode='reviewed' is Wrench.Pro's human-reviewed analysis — cite it. mode='raw' means no review yet: say 'no reviewed Known Issues yet' and…

  • get_maintenance

    Use when the user asks about service intervals, what's due, or what a service should cost. Pass mileage when known. Ranges are estimates and marked approximate — present them that way. 'Pro only' means the job isn't realistic DIY…

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "vehicle-check": {
      "type": "http",
      "url": "https://mcp.wrench.pro/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http wrench https://mcp.wrench.pro/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://mcp.wrench.pro/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
