The Model Context Protocol and Fireproof Demo: JSON Document Server is a simple example of how to use a Fireproof database within an MCP server. It demonstrates a basic JSON document store that exposes Create, Read, Update, and Delete operations and supports querying documents with sorting by any field. Built as an MCP server, it is intended to plug into AI workflows and applications that consume or manage JSON data through the Model Context Protocol. The server is designed to be used with Claude Desktop by adding a Claude configuration that points to the built MCP server binary, enabling seamless data access within AI-assisted environments. Installation is straightforward: run npm install to install dependencies and npm build to build the server. At runtime, the server communicates over stdio and can be debugged with the MCP Inspector, which provides a browser-based debugging UI. This repo serves as a runnable demo for developers exploring MCP-enabled, Fireproof-backed data stores.
