MCP Defender — questions

Answers built from our own checks of this server.

Why is there no uptime for MCP Defender?

MCP Defender 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 pypi package mcp-defender was installed 39 times last week.

How do I connect MCP Defender?

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 mcp-defender straight from pypi; nothing to host, nothing to sign up for.

How many people use MCP Defender?

The pypi package mcp-defender was installed 39 times in the last week. Week over week that is -20%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
