Fireproof MCP Server: A Simple JSON Document Store

Overview: What is Fireproof MCP Server?

The Fireproof Model Context Protocol (MCP) server provides a basic but versatile JSON document store capable of handling Create, Read, Update, and Delete operations with query support for any field. This server is specifically designed to enable seamless integration between AI applications like Claude Desktop and custom data sources. By using the Fireproof MCP server, developers can enhance the functionality of their AI applications by providing structured, searchable, and modifiable datasets that are compliant with the Model Context Protocol.

🔧 Core Features & MCP Capabilities

The Fireproof MCP Server supports core CRUD operations essential for any application needing to manage dynamic data. Additionally, it offers querying capabilities that allow users to search documents based on specific fields. This functionality is crucial for AI applications such as Claude Desktop, which require rapid and efficient access to the information they process.

MCP Protocol Implementation

The Fireproof server implements the Model Context Protocol (MCP) through a simple yet robust protocol stack designed to ensure compatibility with various MCP clients. MCP is analogous to USB-C in that it standardizes interactions between AI applications and data sources, making integration straightforward and efficient. The communication flow involves establishing connections over stdin/stdout, ensuring high reliability and simplicity.

Data Architecture

To efficiently manage JSON documents, the Fireproof server employs a structured storage system optimized for ease of use. Each document is stored with unique keys that allow quick retrieval and updates based on various fields. The schema-less nature of JSON makes it ideal for storing diverse types of data, which is beneficial in AI workflows where data formats can be highly variable.

⚙️ MCP Architecture & Protocol Implementation

The Fireproof server's design leverages the Model Context Protocol to provide a bridge between AI applications and backend data stores. The architecture involves a command-line application that handles request processing and data management according to the MCP specification.

🚀 Getting Started with Installation

To set up the Fireproof MCP server, follow these steps:

1. Install Node.js and npm if not already installed.
2. Run npm install to fetch dependencies.
3. Build the server by executing npm build.
4. Add the server configuration for use with Claude Desktop.

Command Line Configuration

Since MCP servers communicate over stdio, using a tool like MCP Inspector can aid in debugging. To start the inspector:

npm run inspector

This will open a debugging interface accessible via a URL in your web browser.
