FAQ from LiteMCP

What is MCP?

MCP stands for Model Context Protocol. It's a protocol for enabling communication between LLMs and external tools and resources.

What is a Tool in LiteMCP?

Tools in MCP allow servers to expose executable functions that can be invoked by clients and used by LLMs to perform actions.

What is a Resource in LiteMCP?

Resources represent any kind of data that an MCP server wants to make available to clients, such as file contents, screenshots, or log files.

What is a Prompt in LiteMCP?

Prompts enable servers to define reusable prompt templates and workflows that clients can easily surface to users and LLMs.

How can I debug my LiteMCP server?

You can use the mcp-cli tool with the command npx litemcp dev server.js or the MCP Inspector with the command npx litemcp inspect server.js.
