fapi-mcp

MCP server for the FAPI Catalog API — auto-parts OEM cross-references, vehicle applicability, and parts lookup, exposed as tools your AI assistant can call directly.

Drop it into Claude Desktop, Cursor, Cline, or any other MCP-compatible client, and ask things like:

Find cross-references for MANN W 75/3 with at least 2 positive ratings.

Which Toyota models use part AG+251 from MAHLE?

What's the weight of part 10100 from manufacturer 13007?

Production access (your own key) — contact development.iisis@gmail.com or see fapi.iisis.ru.

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "fapi-catalog": {
      "command": "uvx",
      "args": ["fapi-mcp"],
      "env": {
        "FAPI_API_KEY": "<paste-your-key-here>"
      }
    }
  }
}

Restart Claude Desktop. The tools appear automatically.

Cursor

Add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "fapi-catalog": {
      "command": "uvx",
      "args": ["fapi-mcp"],
      "env": { "FAPI_API_KEY": "<paste-your-key-here>" }
