MCP Signer — questions

Answers built from our own checks of this server.

Why is there no uptime for MCP Signer?
MCP Signer 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 @cryptoapis-io/mcp-signer was installed 172 times last week.
How do I connect MCP Signer?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls @cryptoapis-io/mcp-signer straight from npm; nothing to host, nothing to sign up for.
How many people use MCP Signer?
The npm package @cryptoapis-io/mcp-signer was installed 172 times in the last week. Week over week that is -45%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is MCP Signer open source?
Yes — written in TypeScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
