Clef MCP

The Clef MCP server provides AI agents with direct access to Clef's marketplace of 125,000+ businesses for sale. It enables users to search for deals by industry, location, and financial metrics, retrieve detailed deal information including broker contacts, analyze market trends, manage a deal pipeline, and draft CIM requests. The server requires a Clef Dealmaker plan account for authentication via OAuth.

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 clef-mcp https://mcp.tryclef.com/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 clef-mcp --url https://mcp.tryclef.com/mcp

Cursor

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

    }
  }
}

Cline

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