BidBetter MCP

An official MCP server provided by BidBetter that allows AI agents to retrieve collector car valuations based on completed auction sales data. It exposes two read-only tools: list_models to retrieve all models with published values, and value_model to get median prices, percentile bands, and sale counts for specific models and year ranges.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

BidBetter publishes collector-car values from completed auction sales. Call list_models to see what is covered, then value_model for a specific model. Quote the median with its sale count and as-of date, and say it is an estimate from completed sales, not an appraisal. If a car is not covered, say so rather than estimating.

value_model — Value a collector-car model
Advertised by the server during the last successful anonymous check.
Advertised read-only

Median, 25th-75th percentile band and sale count for a specific collector-car model and year range, from completed auction sales. Use for questions like 'what is a 1989 Porsche 911 worth' or 'how much is a 1969 Corvette C3'. Returns one sentence you can quote plus the numbers behind it, with an as-of date and a link to the method. It covers a model and year range, not one individual car.

list_models — List models with a published value
Advertised by the server during the last successful anonymous check.
Advertised read-only

Every collector-car model BidBetter publishes a value for, with its median, band, sale count and page URL. Call this first when you are unsure whether BidBetter covers a car, rather than calling value_model and guessing.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http bidbetter-mcp https://bidbetter.ai/api/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add bidbetter-mcp --url https://bidbetter.ai/api/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable bidbetter-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "bidbetter-mcp": {
      "url": "https://bidbetter.ai/api/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "bidbetter-mcp": {
      "type": "streamableHttp",

    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start bidbetter-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "bidbetter-mcp": {
      "type": "http",
      "url": "https://bidbetter.ai/api/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http bidbetter-mcp https://bidbetter.ai/api/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
