FAQPage Schema
How do I build an MCP server for LLM integration?▼

To build an MCP server for LLM integration, you need to define tools with clear schemas and descriptions, then implement the server using either Python with FastMCP or Node/TypeScript with the MCP SDK. This enables LLMs to interact with external services.

What is the Model Context Protocol used for?▼

The Model Context Protocol (MCP) is used to enable Large Language Models to interact with external services and APIs. It provides a structured way to define tools with schemas and annotations for seamless API integration into systems like JARVIS.

Can I use Python to create an MCP server?▼

Yes, you can use Python to create an MCP server by utilizing the FastMCP framework. The development guide provides a structured workflow for planning and implementing MCP servers using either Python or Node/TypeScript.

How do I integrate an external API into JARVIS?▼

You integrate an external API into JARVIS by building an MCP server that defines the API interactions as tools. These tools require clear schemas, descriptions, and annotations to facilitate seamless integration and allow the LLM to interact with the external service.

What is the best way to define tools in an MCP server?▼

The best way to define tools in an MCP server is to provide clear schemas, detailed descriptions, and proper annotations. This ensures seamless API integration and allows the LLM to correctly understand and execute the available functions.
