Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
vehicle
vehicle_recalls
Official NHTSA safety recalls for a vehicle. Returns campaign id, affected component, the safety consequence, and the free remedy, newest first (max 50). Query by make (optionally model and year) or by a known campaign id. Use this before buying a used vehicle or when a customer asks whether their car has open recalls. A zero count means nothing matched the ingested NHTSA subset — it does not prove the vehicle is recall-free. Costs $0.005 USDC per call via x402 on Base.
vehicle_tsbs
NHTSA Technical Service Bulletins (manufacturer repair guidance for known defects that are not safety recalls). Returns bulletin id, summary, and the fault codes each bulletin names (max 50). Query by make/model/year, or by fault code to find bulletins that address that specific code. Use this after dtc_lookup when you want the manufacturer's documented fix. A zero count means nothing matched the ingested subset. Costs $0.005 USDC per call via x402 on Base.
dtc
dtc_lookup
Look up what a vehicle fault code (OBD-II diagnostic trouble code) means. Returns a reworded definition compiled from open/public sources (with the source and licence per row) plus which makes define the code specifically. Pass 'make' for the make-specific meaning instead of the generic SAE one — the same code can mean different things on different brands. Use this when a scan tool reported a code like P0301, B1318 or U0100; we never guess a meaning (unknown codes return not_found). Descriptions are compilations, not manufacturer verbatim strings, and severity is not guaranteed. Costs $0.006 USDC per call via x402 on Base.
vin
vin_decode
Decode a Vehicle Identification Number into make, model, model year, body class, engine and plant country using NHTSA's public vPIC database. Use this when you have a VIN and need the exact vehicle before looking up recalls or bulletins. Costs $0.005 USDC per call via x402 on Base.

MCPFax Vehicle Diagnostics — questions
Answers built from our own checks of this server.
What can MCPFax Vehicle Diagnostics do?
It exposes 4 tools, read directly from the server on our last check. Among them: dtc_lookup, vehicle_recalls, vehicle_tsbs, vin_decode. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
Is MCPFax Vehicle Diagnostics working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 182 of 182 checks got a reply (100.0%), average response time 97 ms. The bar chart above shows every period we have measured.
Did MCPFax Vehicle Diagnostics ever remove tools?
Yes. find_service_bulletins, get_catalog_attributions, get_catalog_status, list_catalog_vocabulary and 4 more are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.
How do I connect MCPFax Vehicle Diagnostics?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does MCPFax Vehicle Diagnostics need an API key?
No. MCPFax Vehicle Diagnostics completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is MCPFax Vehicle Diagnostics?
It answers our handshake in 97 ms on average, which is faster than 91% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
