How to Connect FavCRM to Claude, Cursor, ChatGPT & v0 (MCP Setup)

FavCRM is an agentic CRM exposed as a single MCP server at https://api.favcrm.io/mcp. Any MCP-compatible client can call it. This guide shows the two ways to connect — point a client at the server, or let the agent sign you up — and the exact, current setup for Cursor, Vercel v0, Claude, and ChatGPT.

Two ways to connect

Path A — bring a key. Create a workspace at favcrm.io/signup, copy your fav_mcp_* key, and put it in your client's MCP config as a Bearer token. Works everywhere immediately.

Path B — agentic signup. Point your client at the server first (no key), then ask the agent: "Sign me up for FavCRM." It calls register_organisation_request, you paste back the 6-digit code from your inbox, and a fav_mcp_* key lands in the chat. No portal, no form. (See how agentic registration works.)

Either way you end up with one key bound to one user and workspace, and 190+ typed tools your agent can call.

Cursor

Cursor reads ~/.cursor/mcp.json (or .cursor/mcp.json in a project). Use an env variable so the key never lands in your repo:

{
  "mcpServers": {
    "favcrm": {
      "url": "https://api.favcrm.io/mcp",
      "headers": {
        "Authorization": "Bearer ${env:FAVCRM_API_KEY}"
      }
    }
  }
}

Export the key where the Cursor process can read it:

export FAVCRM_API_KEY=fav_mcp_xxxxx

Cursor connects over Streamable HTTP, runs tools/list, and surfaces the catalog. Ask it to do real CRM work — no SDK, no REST docs. Full walkthrough: Cursor integration.

Vercel v0

v0 installs FavCRM natively from the Marketplace — set FAVCRM_MCP_URL = https://api.favcrm.io/mcp and v0 calls the tools directly from prompts. Full steps: Vercel v0 integration.

Claude

Claude connects over OAuth 2.0 with PKCE and dynamic client registration. The server is live at api.favcrm.io/mcp; the Connector listing is in review, so today you connect via the OAuth flow / custom connector rather than a one-click directory install. Setup: Claude integration.

ChatGPT

The MCP server is already live; the ChatGPT Apps Directory listing is under review with OpenAI. Once approved it installs from the directory and runs your CRM in plain English. Status and setup: ChatGPT integration.

Other clients

The same endpoint works with Smithery, Windsurf, Continue.dev, Zed, Cline, Roo Code, and Replit Agent — anything that speaks MCP. Point it at https://api.favcrm.io/mcp with a Bearer key.

First command

Once connected, try a real one:

"List my booking services, then create a test booking for tomorrow at 2pm."

The agent chains list_services → get_available_slots → create_booking. If that runs, you're operating a CRM from your editor.
