2. Open Claude Code in that project.
3. Run /mcp, select dealscore, and choose Authenticate.
4. Complete the DealScore email sign-in in the browser and approve access.
5. Ask Claude Code to call score_deal with a year, make, model, asking price, and mileage.

Then run /mcp, pick dealscore, and choose Authenticate. Full setup: /integrations/claude-code.

This command uses OAuth. API keys are for curl and for MCP clients that send headers. Create one on /keys, or follow the request example on /used-car-price-api.

• The command includes --transport http and https://cardealscore.com/api/mcp.
• /mcp has to show dealscore before Authenticate is available. Re-run the add command in the project you opened.
• coverage: cannot_score means the connection worked and the comps were too thin to grade.

score_deal grades a deal. Send asking_price and mileage, plus a VIN or year, make, and model. trim and zip are optional. explain_grade maps a delta_pct to a grade without fetching comps. health reports coverage and limits. Free includes 5 scored calls a month and Builder is $19/mo (founding price) for 1,000 scored calls a month. Only coverage: scored counts, and explain_grade and health are never metered. Plans: /pricing. Argument details: /docs/api. Test arguments in the browser first: /try.

Cursor, Claude Desktop, Codex, ChatGPT. The REST call and a recorded response are on /used-car-price-api. Every client is also listed on /agents.
