What the code does

Evidence

Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

Deletes files or strips permissions src/services/runpod-ssh.ts:196
    { cmd: "ssh", args: [...SSH_OPTS, "-p", String(ep.port), ep.userHost, `rm -rf '${remote}' && mkdir -p '${remote}' && tar --no-same-owner --no-same-permissions -xzf - -C '${remote}'`] },
Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Comfyui MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Comfyui MCP?
Comfyui 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 comfyui-mcp was installed 19 647 times last week.
How do I connect Comfyui 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 comfyui-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Comfyui MCP?
The npm package comfyui-mcp was installed 19 647 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.
Is Comfyui MCP open source?
Yes — it is published under the MIT licence, written in TypeScript, 884 stars on GitHub and 76 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
