JSON Document Collection MCP Server

Use Model Context Protocol with multiple Fireproof JSON document databases

Installation

Add the following to your MCP client configuration file.

Configuration

{
  "mcpServers": {
    "jimpick-mcp-json-db-collection-server": {
      "command": "node",
      "args": [
        "<base-dir>/mcp-json-db-collection-server/build/index.js"
      ]
    }
  }
}

You can run and connect to a multi-database JSON document collection server powered by a Fireproof-backed storage layer. It supports creating multiple databases, performing basic CRUD operations, querying documents by fields, and syncing databases to the cloud for collaboration and sharing.

How to use

You interact with the server through an MCP client to manage several JSON document databases. You can create databases, add, read, update, and delete documents within any database, and run queries that sort results by any field. You can also share a database via the cloud and keep databases synchronized across devices.

How to install

Prerequisites: you need Node.js and npm installed on your system.

npm install
npm build

To run the server locally via the MCP client, install the server package, build it, and then start the server using the configured command. The following steps assume you are placing the server under a base directory you control.

Configuration for Claude Desktop (example MCP URL)

Configure Claude Desktop to load the JSON document collection server by pointing to the local index file after building.

{
  "mcpServers": {
    "json-db-collections": {
      "command": "<base-dir>/mcp-json-db-collection-server/build/index.js"
    }
  }
}
