Questions

What is the Cejel MCP server?

Offline deterministic engineering-trust certificates for repositories, with no telemetry. It is made by @BargLabs and listed in the official MCP Registry as io.github.BargLabs/cejel. MCP (Model Context Protocol) is the open standard that lets AI apps like Claude, ChatGPT and Cursor use outside tools.

How do I add Cejel to Claude?

In Claude Code, run: claude mcp add cejel -- docker run -i --rm ghcr.io/barglabs/cejel@sha256:12372dededed8fbdbe6d1061e6792e3d83e51d0640899dfbc1f8189f8ea67daa

How do I add Cejel to ChatGPT?

ChatGPT only connects to remote MCP servers, and Cejel runs on your own computer. Use it from Claude, Cursor or another app that runs local servers.

How do I add Cejel to Cursor?

Open Cursor settings, go to MCP, choose "Add new MCP server" (or edit ~/.cursor/mcp.json) and add: { "mcpServers": { "cejel": { "command": "docker", "args": [ "run", "-i", "--rm", "ghcr.io/barglabs/cejel@sha256:12372dededed8fbdbe6d1061e6792e3d83e51d0640899dfbc1f8189f8ea67daa" ] } } }

Does Cejel work right now?

It runs on your own computer, so it works once you install it. There is no remote server for us to check.
