Overfit MCP MCP server

An official MCP server provided by Overfit that exposes over 190,000 German public tenders and six procurement law calculators. It allows AI agents to search for open tenders by keyword, region, or CPV code, and deterministically calculate legal deadlines, thresholds, and evaluation matrices with cited legal bases (GWB/VgV/VOB/A-EU/UVgO). The server operates without authentication, returning JSON responses with source links for verification.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http overfit-mcp https://www.overfit.de/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 overfit-mcp --url https://www.overfit.de/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable overfit-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "overfit-mcp": {
      "url": "https://www.overfit.de/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.

Cline configuration

{
  "mcpServers": {
    "overfit-mcp": {
      "type": "streamableHttp",
      "url": "https://www.overfit.de/mcp",
      "disabled": false
    }

}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start overfit-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "overfit-mcp": {
      "type": "http",
      "url": "https://www.overfit.de/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 overfit-mcp https://www.overfit.de/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

    }
  }
}

Windsurf

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

Windsurf configuration

{
  "mcpServers": {
    "overfit-mcp": {
