Btc Address MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Btc Address MCP?
Btc Address MCP runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @mrfentmen/btc-address-mcp was installed 558 times last week.
How do I connect Btc Address MCP?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls @mrfentmen/btc-address-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Btc Address MCP?
The npm package @mrfentmen/btc-address-mcp was installed 558 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Btc Address MCP open source?
We cannot say either way: written in TypeScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
