Connection Setup

The Connfig MCP server endpoint:

https://mcp.connfig.com/mcp

The server uses the Streamable HTTP transport, and all requests go to this single endpoint as POST.

Authentication

There are two paths; both work through the standard Authorization: Bearer header.

1. API key (cnfg_)

Generate a key in the app under Profile → API Keys. Keys start with the cnfg_ prefix and are shown only once at creation — store them somewhere safe. Add this header to your requests:

Authorization: Bearer cnfg_YOUR_API_KEY

An API key is the recommended path for clients that use a configuration file, such as Claude Code, Claude Desktop, Cursor, and VS Code.

2. OAuth (automatic for claude.ai)

Claude.ai connectors do not need an API key. The server supports OAuth discovery standards (protected resource metadata) and Dynamic Client Registration (DCR): you only give claude.ai the URL, sign in on the Connfig login screen that opens — the rest is automatic.

Setup per client

claude.ai (web) — recommended, no API key needed

1. Settings → Connectors → Add custom connector
2. Enter this in the URL field: https://mcp.connfig.com/mcp
3. Leave the OAuth Client ID/Secret fields empty and press Add
4. Sign in with your account on the Connfig login screen that opens

Claude Code (terminal)

First create an API key and put it in place of cnfg_YOUR_API_KEY:

claude mcp add --transport http connfig https://mcp.connfig.com/mcp \
  --header "Authorization: Bearer cnfg_YOUR_API_KEY"

Cursor / Windsurf / VS Code (mcp.json)

{
  "mcpServers": {
    "connfig": {
      "type": "http",
      "url": "https://mcp.connfig.com/mcp",
      "headers": { "Authorization": "Bearer cnfg_YOUR_API_KEY" }
    }
  }
}

Claude Desktop (claude_desktop_config.json)

{
  "mcpServers": {
    "connfig": {
      "command": "npx",
      "args": [
        "mcp-remote", "https://mcp.connfig.com/mcp",
        "--header", "Authorization: Bearer cnfg_YOUR_API_KEY"
      ]
    }
  }
}
