MCP Server Configuration

What is MCP Server Configuration?

MCP Server Configuration is a fixed configuration repository for the Model Context Protocol (MCP) server that resolves the ERR_MODULE_NOT_FOUND error related to the zod-to-json-schema dependency. It is intended for developers using the @modelcontextprotocol/server-filesystem package who encounter that import issue.

How to use MCP Server Configuration?

Clone the repository, run npm install to install dependencies, then start the server with npm start. An alternative quick fix involves creating a new Node.js project, installing @modelcontextprotocol/server-filesystem, zod, and zod-to-json-schema explicitly, adding "type": "module" to package.json, and creating a simple index.js that imports and creates the server.
