MCP Server - OpenFunnel

Endpoint: https://agents.openfunnel.dev/mcp — a remote MCP server that exposes the Agent Primitives as tools. Authentication is handled automatically over OAuth; no API key to copy.

The OpenFunnel Primitives MCP is a hosted Model Context Protocol server. Point any MCP client at it and your agent can call OpenFunnel’s primitives directly — lookalike search, technography search, deep research, and the supporting helpers — scoped to your account. It’s the same building blocks as the Agent Primitives API, wrapped as MCP tools so you don’t have to write any HTTP glue.

Authentication

The server is a standard OAuth 2.1 resource server, so connecting is a one-time browser sign-in — the client discovers the flow, you approve access, and it stores the token. There is no X-API-Key header to manage; the server resolves your OpenFunnel key from your account after you consent.

Add the server

Add https://agents.openfunnel.dev/mcp as a remote/HTTP MCP server in your client (see below).

The client opens a browser window. Sign in with your OpenFunnel account and approve the connection on the consent screen.

Call tools

Your agent can now call the tools listed below. Tokens refresh automatically.

Claude
Cursor

In Claude (Settings → Connectors → Add custom connector), add a remote MCP server with URL:

https://agents.openfunnel.dev/mcp

Claude will walk you through the OAuth sign-in the first time you use it.

Add the server to your MCP config (~/.cursor/mcp.json):

{
  "mcpServers": {
    "openfunnel": {
      "url": "https://agents.openfunnel.dev/mcp"
    }
  }
}

Reload, then authenticate when prompted.
