Mempool.space is a community-built MCP server published by alexandresanlim that provides AI assistants with tools and capabilities via the Model Context Protocol. Access real-time Bitcoin data, transaction details, and mining stats via the Mempool.space API for developers and trader It is categorized under finance, analytics data. This server exposes 31 tools that AI clients can invoke during conversations and coding sessions.
You can install Mempool.space in your AI client of choice. Use the install panel on this page to get one-click setup for Cursor, Claude Desktop, VS Code, and other MCP-compatible clients. This server runs locally on your machine via the stdio transport. This server supports remote connections over HTTP, so no local installation is required.

Add new capabilities to Claude beyond text generation
Example
Access external data sources, execute code, interact with tools and services
Transform Claude from chatbot to action-taking agent
Provide Claude with access to relevant context and data
Example
Load project documentation, access knowledge bases, query databases
Get more accurate, context-aware responses
Automate multi-step workflows combining AI and external tools
Example
Research → Summarize → Create document → Send notification
Complete complex tasks end-to-end without manual steps
Share your MCP server with the developer community
According to our notes, Mempool.space benefits from clear Model Context Protocol framing — fewer ambiguous “AI plugin” claims.
Useful MCP listing: Mempool.space is the kind of server we cite when onboarding engineers to host + tool permissions.
Mempool.space has been reliable for tool-calling workflows; the MCP profile page is a good permalink for internal docs.
Strong directory entry: Mempool.space surfaces stars and publisher context so we could sanity-check maintenance before adopting.
I recommend Mempool.space for teams standardizing on MCP; the explainx.ai page compares cleanly with sibling servers.
Mempool.space is among the better-indexed MCP projects we tried; the explainx.ai summary tracks the official description.
We evaluated Mempool.space against two servers with overlapping tools; this profile had the clearer scope statement.
According to our notes, Mempool.space benefits from clear Model Context Protocol framing — fewer ambiguous “AI plugin” claims.
Mempool.space is a well-scoped MCP server in the explainx.ai directory — install snippets and categories matched our Claude Code setup.
We wired Mempool.space into a staging workspace; the listing’s GitHub and npm pointers saved time versus hunting across READMEs.

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.
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!
or
git clone https://github.com/alexandresanlim/mempool-mcp-server.git
npm install
npm run build
npm run server
"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. 🎉
Made with ❤️ by a bitcoiner. Enjoy!

Steps
Troubleshooting
✓ Do
✗ Don't
💡 Pro Tips
Architecture
Model Context Protocol standardizes how AI hosts (Claude, Cursor) communicate with external tools and data sources through server implementations.
Protocols
Compatibility
✓ Use when
Use when you need Claude to access external data, execute actions, or integrate with tools. Best for extending AI capabilities beyond conversation.
✗ Avoid when
Avoid when native integrations exist (use official APIs directly), for real-time critical systems, or when security/compliance requires zero external dependencies.
