Overview

carvector-mcp MCP server connects MCP clients to the CarVector API for structured vehicle specifications, federal safety data, and OBD-II code references. It runs locally over stdio with an API key or can be accessed through CarVector's hosted HTTP MCP endpoint. Reach for it when an agent needs vehicle-specific facts, recall information, owner-complaint signals, service-bulletin indexes, defect investigations, or diagnostic-code classifications.

Use cases

  • Resolve vehicle trims and specifications
  • Check federal recalls for a vehicle
  • Review complaint patterns and defect investigations
  • Look up OBD-II code severity and safety flags

Key features

  • Vehicle search by year, make, and model
  • Detailed engine, drivetrain, and body specifications
  • Federal recall and defect-investigation data
  • Owner complaints and service-bulletin indexes
  • OBD-II code classification

How Carvector MCP works

What carvector-mcp MCP server does

carvector-mcp MCP server gives an MCP-compatible agent access to vehicle information served by the CarVector API. Available data includes vehicle records, representative images, engine and drivetrain specifications, federal recalls, owner complaints, manufacturer service-bulletin indexes, federal defect investigations, and OBD-II diagnostic trouble code classifications.

The vehicle catalog is organized by year, make, model, trim, and engine variant. Agents can first resolve a vehicle with search_vehicles, then use its identifier for more detailed requests. The DTC reference returns a code's title, category, severity, and safety or emissions flags.

How it works

The package is a thin client rather than a local database. Each tool call is forwarded to api.carvector.io and authenticated with the configured CarVector API key. No vehicle data is bundled with the package, so returned information depends on the API and the account's plan and rate limits.

The normal flow is to search for a vehicle, retrieve its full record, and then request related recalls, complaints, technical service bulletins, or investigations. lookup_dtc accepts an OBD-II code directly and does not require a vehicle lookup. The MCP client itself uses API-key authentication; x402 payment support applies to direct HTTP API calls, not this package.

Setup and configuration

Create a CarVector account and obtain an API key, then provide it as CARVECTOR_API_KEY in the MCP client's server configuration. A stdio setup can run the package with npx -y carvector-mcp. The command-line --key option is also available, although keys passed as arguments may be visible in process listings.

Clients that support HTTP MCP can instead connect to https://api.carvector.io/v1/mcp and send the API key as a Bearer authorization header. The local package exits without an API key. Calls count against the account's plan limit and appear in the CarVector dashboard.

Tools and capabilities

  • search_vehicles: Finds matching vehicles by year, make, and model, returning identifiers and specifications.
  • get_vehicle: Returns detailed vehicle data, including engine, drivetrain, body, representative image, and recall count.
  • get_recalls: Retrieves federal recall campaigns with component, summary, consequence, and remedy fields.
  • get_complaints: Provides component-level owner-complaint aggregates and recent filings. This requires the Pro plan.
  • get_tsbs: Returns a manufacturer's service-bulletin index and requires the Business plan. It provides bulletin metadata, not the bulletin documents.
  • get_investigations: Returns federal defect investigations and requires the Business plan.
  • lookup_dtc: Classifies an OBD-II code by title, category, severity, and safety or emissions flags.

Limitations and notes

carvector-mcp MCP server provides reference data; it does not perform repairs or provide repair-cost economics. DTC responses are classifications rather than a complete diagnostic procedure. Vehicle images are representative illustrations, not photographs.

Complaints, service bulletins, and investigations have plan requirements. The client has no built-in dataset and cannot return information independently of the CarVector API. The repository describes the client as open source under the MIT license, while the underlying data is served by CarVector.

The client sends the API key to the CarVector host and is described as having no telemetry, analytics, disk writes, or additional hosts. The repository lists the official MCP SDK as its only package dependency.

Frequently Asked Questions about Carvector MCP

carvector-mcp is an MCP server that connects AI clients to the CarVector API. Its main tools search vehicles, retrieve detailed specifications, check recalls, complaints, service bulletins, and investigations, and look up OBD-II diagnostic codes with severity and safety or emissions classifications.

Install it by configuring your MCP client to run `npx -y carvector-mcp` and setting the `CARVECTOR_API_KEY` environment variable. Obtain the key from CarVector, restart the client, and then use the vehicle and diagnostic tools.

Yes, the README names Cursor as a supported MCP-capable client. Configure Cursor with the stdio command and `CARVECTOR_API_KEY`, or use the hosted HTTP MCP endpoint if your Cursor setup supports HTTP MCP.

It can return vehicle specifications, representative images, federal recalls, owner-complaint aggregates and recent filings, service-bulletin indexes, federal defect investigations, and OBD-II code classifications. Complaints require Pro, while service bulletins and investigations require Business.

No, the MCP client does not make x402 payments and requires an API key. x402 is available when calling the CarVector HTTP API directly, where requests can be paid per call.
