Configuring MCP Servers

Infinity Code supports MCP (Model Context Protocol) servers as tool sources. Any MCP server works through a built-in proxy layer — no changes to the server needed.

Configuration Files​

There are two levels of configuration:

  • User-level: ~/.infinity/rap.json — applies to all repos
  • Project-level: .infinity/rap.json in a repo — applies only to that repo

Both are merged at startup. Project-level entries are combined with user-level entries.

Adding a Local MCP Server​

Add an entry to the tool_sets array in your rap.json:

{
  "tool_sets": [
    {
      "type": "mcp_server",
      "name": "my-server",
      "command": ["path/to/server", "arg1", "arg2"],
      "env": { "KEY": "value" }
    }
  ]
}

The command array is the command and arguments to spawn the MCP server as a stdio subprocess. The optional env object sets environment variables for the process.

Adding a Remote HTTP MCP Server​

For MCP servers accessible over HTTP:

{
  "tool_sets": [
    {
      "type": "http_mcp_server",
      "name": "my-remote-server",
      "url": "https://example.com/mcp",
      "headers": { "Authorization": "Bearer <token>" }
    }
  ]
}
