What it does
The OdoTrace connector lets Claude or ChatGPT run the same free checks as this website while you talk about a car. You paste a VIN from a listing, the assistant calls OdoTrace, and it answers from the records it gets back, naming each source and its limits.
It uses the Model Context Protocol (MCP), an open standard for giving assistants access to outside tools. The connector only reads data. It cannot change anything, and it needs no sign-in.
Server address: https://api.odotrace.com/mcp
Start with our free AI VIN-check guide for copyable prompts, a tool-by-tool comparison and examples of how to read sources, verdicts and gaps. You can also run the free check in your browser.
Add it to Claude
- Open Customize > Connectors in Claude.
- Choose to add a custom connector.
- Name it OdoTrace and paste the server address
https://api.odotrace.com/mcp. Leave the sign-in fields empty. - In a chat, turn the connector on from + > Connectors, then ask about a car. Claude asks before it runs a check for the first time.
Add it to ChatGPT
- Open chatgpt.com/plugins.
- Select the plus button, then Add custom MCP server.
- Name it OdoTrace, enter the server address
https://api.odotrace.com/mcpas a public endpoint and choose no authentication. - Confirm, then start a new chat, type
@and pick OdoTrace.
Menu names in both products change from time to time, and custom servers can be limited by your plan or workspace settings. Any other assistant or tool that supports remote MCP servers over Streamable HTTP can use the same address.
What you can ask
- “Decode this VIN and tell me whether it matches the advert: 1HGCM82633A004352.”
- “Check the official mileage records for this VIN. Is there any sign of a rollback?”
- “This Dutch car has plate XX-123-X. What does the RDW say about its odometer?”
- “Which recalls were published for a 2015 Volkswagen Golf?”
- “Is 90,000 km low for a 2012 Ford Focus?”
- “Can OdoTrace check the mileage of a car imported from Poland?”
The tools
| Tool | You give | It returns |
|---|---|---|
decode_vin | VIN | Make, model, model year, body, engine, fuel and plant where the VIN pattern is known, and an estimated build period for some manufacturers. |
check_mileage_history | VIN, optionally a Dutch plate | Official odometer readings found for the car, each source’s status, gaps, and a rule-based rollback verdict. |
get_recalls | Make, model, year | Recall notices from US NHTSA, EU Safety Gate, Germany’s KBA and France’s RappelConso, kept separate. |
get_typical_mileage | Make, model, year | Median and 10th to 90th percentile odometer readings from UK MOT tests in 2023, and a Lithuanian sample where one exists. |
get_us_model_data | Make, model, year | US NHTSA crash-test ratings and US EPA fuel economy. |
get_coverage | Nothing | Which sources OdoTrace covers, what each needs and what it cannot show. |
Limits you should know
- It is a pre-check, not a full history. Mileage readings come from UK MOT tests, Czech records, New York inspections and the Dutch odometer verdict. A car never inspected in one of those places returns no readings. No readings is a gap in coverage and does not mean the mileage is genuine. The coverage page has the detail.
- A rollback is flagged only on hard evidence: a later official reading that is lower than an earlier one. Anything less is reported as insufficient data.
- Dutch results belong to the plate. The Dutch register’s open data has no VIN, so a plate result is not proof that it is the same car as the VIN you gave.
- Recalls are model-level. They do not show whether one particular car is affected or already repaired. Ask the manufacturer or a dealer.
- No accident, theft, finance or owner information. OdoTrace does not have it and the connector does not return it.
- The assistant writes the answer. OdoTrace supplies records and caveats; the assistant decides how to word them and can get things wrong. Check anything that matters in the full report, and inspect the car and its paperwork before you buy.
- The website does more. The Danish inspection pilot, the Norwegian registry lookup, the separate UK plate lookup, Finnish fleet comparisons and links to each country’s official lookup are on the website only.
Privacy
The connector receives only what the assistant sends it: a VIN, a Dutch plate if you gave one, or a make, model and year. It does not receive your conversation, your name or your account details. OdoTrace handles those identifiers exactly as it does for a check on this website, including which official sources receive them and how long results are kept. The privacy notice covers the connector in its own section. The company that runs your assistant handles your conversation under its own terms.
Fair use
The connector is free and shares limits with everyone else using it. It is meant for people checking individual cars in a conversation. Bulk or scheduled lookups are not allowed, as the terms of use explain, and a check can be refused for a short time when the shared limit is reached.
Support
Questions, a result that looks wrong, or a connector that will not connect: email [email protected]. Leave the VIN out unless it is needed to reproduce the problem. The contact page says what else to include.
