MCP Client¶
The MCP Client worker connects to an external AI model using the Model Context Protocol (MCP), sends a prompt, and returns the model's response. Use it to route workflow prompts through a specific model and API key combination, or to integrate with MCP-compatible services outside the Everysk platform.
