Overview

AI-generated overview

Remote MCP server giving assistants access to collector-car auction history, live listings, bid trails and market statistics.

What you can do
Look up completed collector-car auction results across major auction houses and platforms, including Bring a Trailer, Cars & Bids, Hagerty, PCAR Market, Gooding & Co and RM Sotheby's. Browse live auction listings and review bid history. Explore vehicle makes and models. Retrieve pricing statistics and market trends for collector cars.
When to use it
Useful when an assistant needs collector-car market data: researching past sale prices, tracking live auctions and bids, or comparing makes and models and market trends.
Requirements
A remote MCP endpoint over Streamable HTTP. OAuth authentication is required; clients without OAuth support may use an Old Cars Data API key via a custom authorization header where the client allows it. Network access to the provider's API is needed.
Before you install
Requires an Old Cars Data account and OAuth authorization or an API key, which is a credential to keep private. The server is read-only market data, but queries are sent to a third-party service.

Installation

In SourceWeft

  1. Open Old Cars Data in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.oldcarsdata%2Fmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.
