Toyota parts MCP server

Ask in plain English, get part numbers and prices

The part number comes out of the catalog. The prices come out of the supplier records, and every one of them arrives carrying the date it was last checked, so nothing is ever presented as today's number when it isn't.

Those rows are read from the same price records get_part_prices reads — they are not a mock-up, and they will be different by the time you run it. See the full comparison for 04465-60120 →

One URL, three clients

Every client below points at the same address. Authentication is OAuth and the client discovers it on its own — a Cruisin4Parts sign-in window opens, you approve it once, and that is the setup. There is no key to paste.

Fourteen tools, one of them Premium

Each tool does what you could do yourself by clicking around the site, on the same terms and at the same cost. Where the website charges a search, the tool charges a search. Where the website is free, so is the tool.

• find_parts_for_vehicleFree

  Part numbers for a truck and a job, described in plain English — "timing belt for a 2003 4Runner".

• lookup_part_numberFree

  What a number is, what it fits, and whether it has been superseded. Deliberately returns no price.

• get_part_prices1 search

  The cached comparison: the cheapest ten suppliers with availability, the date each price was last checked, and a link to buy.

• get_live_prices1 search

  Starts a fresh price check across the supplier roster and returns a handle immediately. Same meter as the part page.

• get_price_statusFree

  Polls that handle for prices as they land. Free — you already paid to start the lookup.

• create_projectFree

  Saves a parts list to your account and hands back its URL. Nothing to claim, nothing to confirm.

• list_projectsFree

  Your build lists, newest first.

• get_projectFree

  One list in full — every line, its best known price, and the total.

• add_project_partFree

  Adds a part number to one of your lists.

• remove_project_partFree

  Takes a line back off.

• update_project_partFree

  Changes a line — quantity, notes, whether it is already bought.

• rename_projectFree

  Renames a list. The slug changes with it, and the tool returns the new one.

• refresh_project_pricesPremium

  Re-checks every line of a list at once. Bulk refresh is Premium on the website too.

• pingFree

  Confirms the connection and which account is signed in. Useful exactly once, on the day setup goes wrong.

It's free. Premium removes the meter.

• Catalog lookups and build lists are free on any signed-in account, unmetered. Finding part numbers, reading a list, adding a line, renaming it — none of that is counted.
• A price comparison costs one search — the same one the part page costs. Two if you hand it a ZIP for shipping. Asking for the same part again the same day is free. A free account gets 20 searches a month, and the connector spends from that same allowance rather than a separate one.
• Premium and Project Pass have no meter, so on those accounts everything above is uncounted.
• One tool needs Premium: refresh_project_prices, which re-checks every line of a project at once. Bulk refresh is Premium on the website too. Refuse it and the tool says so in words — your assistant reads you the reason rather than a 403.

What it will not do

• It won't invent a price. Every number carries the date it was last checked. Where there is nothing on record, the tool returns no price and hands over the part page so you can run the live search yourself.
• Aftermarket never wins. RockAuto listings come back labelled as aftermarket and are never counted as the best price — the same rule the part page follows. Ask for OEM only and they are left out entirely.
• It only touches your own lists. A project your account doesn't own gets the same answer as one that doesn't exist, so nobody's assistant can go looking through anyone else's build.
• It doesn't buy anything. No cart, no checkout, no payment method. You get the supplier's link and place the order.
• Buy mode stays on the website. Grouping a list by supplier, buy plans and shipping estimates to your door have no connector representation at all.

What is the Cruisin4Parts MCP server?

An MCP (Model Context Protocol) server that lets an AI assistant read the Cruisin4Parts catalog and price records directly. Instead of you searching part numbers and comparing suppliers in a browser, the assistant calls the same data the website runs on and shows you the result.

Does the connector cost extra?

No. It is part of your Cruisin4Parts account and there is no separate plan for it. Catalog lookups and everything to do with your build lists are free on any account. A price comparison spends one search from the same monthly allowance the website spends from — two if you give it a ZIP for shipping — and Premium has no meter. One tool, the bulk refresh of a whole project, needs Premium, because bulk refresh is Premium on the website too.

Which assistants can use it?

Claude on claude.ai, Claude Code, and ChatGPT on the web in developer mode. Any MCP client that speaks streamable HTTP and OAuth should work; those three are the ones that have been set up and tested end to end.

Do I need an API key?

No. Authentication is OAuth and the client discovers it from the server. You paste one URL, a Cruisin4Parts sign-in window opens, you approve it, and that is the whole setup. There is no key to generate, copy or rotate.

Can it buy parts or spend money?

No. The connector has no checkout, no cart and no payment method. Every price comes back with the supplier's own URL and you place the order yourself. The only thing it spends is a search from your monthly allowance, and only on the two price tools.
