General
MCP Server
Overview
Knot provides an MCP server for the API to allow you to interact with the API via natural language prompting. The MCP server provides a tool for each endpoint on the API, as well as a tool to search these docs themselves, all via natural language prompting. This functionality is particularly useful when integrating Knot for the first time via Knot’s development environment. The MCP server (once installed into your IDE) can allow you to work with the API more quickly. The MCP server for Knot’s API exists athttps://docs.knotapi.com/mcp.
Example Use Cases
