Auto.dev

Automotive data for AI agents — via MCP tools, CLI commands, SDK methods, or direct API calls.

Detect Your Surface

Check in this order. Use the first one available:

1. MCP — Check if auto_decode is in your available tools. If yes: use auto_* tools for everything. Do NOT make raw HTTP calls. To install: npx @auto.dev/sdk mcp install (installs globally and configures Claude Code, Claude Desktop, Cursor, Windsurf, VS Code Copilot, Cline, Zed).

2. CLI — Run auto --version. If installed: authenticate once with auto login (OAuth — no API key needed), then use auto commands. To install: npm install -g @auto.dev/sdk or use npx @auto.dev/sdk <command> without installing.

3. SDK — Check if @auto.dev/sdk is in project dependencies. If yes: use typed SDK methods. See code-patterns.md for all methods. To install: npm install @auto.dev/sdk

4. Direct API — Check for AUTODEV_API_KEY env var. If not set: ask the user for it or direct them to https://auto.dev/pricing (free Starter plan).

MCP Tools

If MCP tools are available, this is your only section. Use auto_docs to look up parameters and response shapes before calling an unfamiliar endpoint.

auto_docs listings      # see all listing filters
auto_docs payments      # see payment params
auto_docs vin-decode    # see VIN decode response shape

| Tool | Description | Plan | |------|-------------|------| | auto_decode | Decode a VIN | Starter | | auto_listings | Search listings with filters | Starter | | auto_photos | Get vehicle photos | Starter | | auto_specs | Vehicle specifications | Growth | | auto_build | OEM build data ($0.10/call) | Growth | | auto_recalls | Safety recalls | Growth | | auto_payments | Payment calculations | Growth | | auto_apr | Interest rates | Growth | | auto_tco | Total cost of ownership | Growth | | auto_open_recalls | Open/unresolved recalls | Scale | | auto_plate | Plate to VIN ($0.55/call) | Scale | | auto_taxes | Taxes and fees | Scale | | auto_docs | Search bundled API documentation | — | | auto_config_set | Set a config value (e.g. raw: true) | — | | auto_config_get | Get a config value or list all settings | — |

API metadata is stripped from MCP tool responses by default. Use auto_config_set with key: "raw" and value: "true" to get full responses.

If MCP tools are available, skip to Important Rules below.

CLI Quick Reference

Install: npm install -g @auto.dev/sdk (or use npx @auto.dev/sdk without installing) Authenticate once: auto login

auto decode <vin>
auto photos <vin>
auto listings --make Toyota --year 2024 --price 10000-40000 --state CA
auto specs <vin>
auto build <vin>
auto recalls <vin>
auto open-recalls <vin>
auto payments <vin> --price 35000 --zip 90210 --down-payment 5000
auto apr <vin> --year 2024 --make Honda --model Accord --zip 90210 --credit-score 750
auto tco <vin> --zip 90210
auto taxes <vin> --price 35000 --zip 90210
auto plate <state> <plate>
auto usage
auto docs [query]        # search bundled docs
auto explore [endpoint]  # browse params and mappings

All commands support --json, --yaml, --raw, and --api-key <key> flags.

API metadata is stripped by default — you get clean vehicle data. Use --raw to see the full API response.

auto config set raw true    # always show full responses
auto config get raw         # check current value
auto config list            # show all settings

Direct API Quick Reference

Use these only when MCP and CLI are unavailable.

V2 (base: https://api.auto.dev): Authorization: Bearer {key} or ?apiKey={key} V1 (base: https://auto.dev/api): ?apikey={key} (query string only)

| Endpoint | Plan | Required Params | |----------|------|-----------------| | GET /listings?filters | Starter | See v2-listings-api.md | | GET /listings/{vin} | Starter | — | | GET /vin/{vin} | Starter | — | | GET /photos/{vin} | Starter | — | | GET /specs/{vin} | Growth | — | | GET /build/{vin} | Growth | — ($0.10/call) | | GET /recalls/{vin} | Growth | — | | GET /tco/{vin} | Growth | — | | GET /payments/{vin} | Growth | price, zip | | GET /apr/{vin} | Growth | year, make, model, zip, creditScore | | GET /openrecalls/{vin} | Scale | — | | GET /plate/{state}/{plate} | Scale | — ($0.55/call) | | GET /taxes/{vin} | Scale | — |

V1 supplemental (no V2 equivalent): /api/models, /api/cities, /api/zip/{zip}, /api/autosuggest/{term}

Before making any Direct API call, read the relevant reference file for full parameter names and examples. Full parameter reference: v2-listings-api.md | v2-vin-apis.md | v2-plate-api.md | v1-apis.md

Common Gotchas (All Surfaces)

These parameter names do NOT exist on the Direct API — agents hallucinate them frequently:

make=    ← use vehicle.make
model=   ← use vehicle.model
state=   ← use retailListing.state
price=   ← use retailListing.price (on /listings), or price= (on /payments, /taxes)
rows=    ← use limit
sort=    ← no sort parameter exists
_order=  ← no sort parameter exists

MCP and CLI handle these mappings automatically. This only matters for Direct API calls.

Plans & Pricing

See pricing.md for full per-call costs and upgrade links.

| Plan | Monthly | Includes | |------|---------|----------| | Starter | Free + data fees | VIN Decode, Listings, Photos (1,000 free calls/mo) | | Growth | $299/mo + data fees | + Specs, Recalls, TCO, Payments, APR, Build | | Scale | $599/mo + data fees | + Open Recalls, Plate-to-VIN, Taxes & Fees |

All plans charge per-call data fees on every request. Growth/Scale have no cap on volume but data fees still apply.

Important Rules

  • Before batch operations, call the endpoint once with a single item to see the actual response shape. Do not guess field names or nesting — inspect the real response first.
  • Include ALL fields from the API response unless the user explicitly says to exclude some.
  • Small results (<10 items, single VIN): Display inline as formatted table
  • Large results (10+ listings): Ask user preference, default to CSV export
  • Always support: CSV, JSON export when user requests
  • Chain APIs when the query spans multiple endpoints — MCP tools and CLI commands can be called in parallel

Deep Reference

MCP or CLI: use auto_docs [query] or auto docs [query] for live parameter lookup. Full reference: https://docs.auto.dev/v2/cli-mcp-sdk

SDK: see code-patterns.md for typed methods and response format.
