DTC Lookup

What it grounds

DTC Lookup explains OBD-II diagnostic trouble codes such as P0301 or U0100. It returns the code's system and standard title, which warning light it turns on, and on paid plans the full description, likely causes ranked by likelihood, symptoms, repair difficulty, estimated cost and labor hours, and related codes. Carmaker-specific codes are covered for 32 makes.

Ways to ground with it

Ground answers in real data

Enable DTC Lookup and it becomes a tool your agent calls over MCP to check itself against live data before it answers — grounding the response instead of guessing.

On the same endpoint and key

DTC Lookup rides the one VerveContext MCP endpoint alongside 300+ other sources, so adding it to an agent is a toggle, not an integration.

Traceable and current

The agent pulls dtc lookup at answer time and can carry the source with the result, so the reasoning stays current and auditable.

Connect over MCP

Point your agent framework at the VerveContext endpoint. Every enabled source — this one included — becomes a tool the model can call. No per-source plumbing.

How to ground an agent in it over MCP.

How do I give my agent DTC Lookup?

Enable it on VerveContext and point your agent framework at the VerveContext MCP endpoint. DTC Lookup then appears to the model as a tool named dtclookup, which it calls when a task needs it — no per-source plumbing.

Which agents and frameworks can use it?

Any MCP client — Claude, Cursor, LangChain, and custom agents all speak the Model Context Protocol. DTC Lookup is exposed as a standard tool, so nothing source-specific is required.

Can the agent cite DTC Lookup?

DTC Lookup is a capability rather than a factual source, so it isn't something to "cite" — but it runs on the same real-data layer, over the same MCP endpoint and key as every grounding source.

How many credits does a DTC Lookup call cost?

Each call costs 1 credit. Scoped keys let you grant an agent only the sources it should reach, and usage logs show exactly what was pulled to ground each answer.

How current is the data?

DTC Lookup is served live from APIVerve's production data engine and pulled at the moment the agent calls it, so answers reflect the world now rather than the model's training cutoff.

Where does the data come from, and what shows on my bill?

VerveContext runs on APIVerve, our production data engine; DTC Lookup is one of 300+ sources on the same key. Invoices and card statements show APIVERVE.
