Tool calling

With RunRL, you can train agents to use MCP tools. Any unauthenticated remote MCP server should work. To host MCP servers, you can use Cloudflare or Klavis.

To start training with an MCP, select a Qwen model and multi-turn environment. Then, click "Add tools" and "Create tool" to connect to the MCP.

During training, a list of the MCP tools will be added to your prompts, and tool calls in the agent loop will be processed automatically.
