Frequently Asked Questions
Everything you need to know about MCP tool generation.
MCP (Model Context Protocol) is a standard protocol that allows AI agents like Claude to connect with external tools and services. An MCP tool is a function that an AI can call to perform actions such as fetching weather data, reading files, or making API requests. Our MCP tool generator helps you create these tools from simple JSON definitions.
After generating your MCP server code, save it to a file and add it to your Claude Desktop configuration. Go to Settings → Developer → Edit Config, then add your server to the mcpServers object. Claude will automatically discover and use the tools you define.
Yes, our MCP tool generator is completely free to use. There is no signup required, no API key needed, and no usage limits. You can generate as many MCP servers as you need for your AI projects.
JSON to MCP conversion is the process of transforming a JSON schema that describes a tool's parameters into a complete, production-ready MCP server implementation. Our generator takes your JSON definition and outputs TypeScript code that implements the Model Context Protocol, handling tool registration, request routing, and response formatting automatically.
Yes, all code generated by our MCP tool generator is yours to use in any project, including commercial applications. The generated code uses the open-source MCP SDK and standard TypeScript, with no proprietary dependencies or licensing restrictions.
To run the generated MCP server locally, you need Node.js installed. The generator itself runs entirely in your browser with no installation required. Simply paste your JSON schema, click Generate, and copy the resulting TypeScript code to your project.
