🤖 What is MCP?
Model Context Protocol (MCP) is a standard for tool providers to communicate with AI clients via standard input/output. This server lets you plug Bitcoin data tools into any MCP-compatible client.
⚡ Quick Start: Use in Your MCP Client
You can configure this server as a tool provider in your MCP Client such Claude, Cursor, VsCode and others:
"mempool-mcp-server": {
"command": "npx",
"args": [
"@sanlim/mempool-mcp-server"
]
},TIP
To connect locally for privacy and unlimited calls, you can pass the base mempool API URL as an environment config from your local Bitcoin node such as Umbrel, MyNode, etc. See below:
"mempool-mcp-server-local": {
"command": "npx",
"args": [
"@sanlim/mempool-mcp-server"
],
"env": {
"MEMPOOL_BASE_URL": "http://umbrel.local:3006/api"
}
},Check this working with "mempool url" text on your MCP Client.
Enjoy!

🛠️ Using a Local Build
Clone this repository:
git clone https://github.com/alexandresanlim/mempool-mcp-server.gitInstall and build:
npm install
npm run build
npm run serverConfigure your MCP client:
"mempool-mcp-server-debug": {
"command": "node",
"args": [
"...replace_to_path_of_project/mempool-mcp-server/build/main.js"
]
},The server will start and listen for MCP requests via standard input/output. 🎉
