Cejel

Overview

Cejel is a Model Context Protocol (MCP) server: Offline deterministic engineering-trust certificates for repositories, with no telemetry. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.

It runs locally: the Docker image ghcr.io/barglabs/cejel@sha256:f1cd2356cc0072ad08e24fcddc379206ee07f5699b9a633164326917f665b6d6 speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v0.4.5, published under the AGPL-3.0 license, with source at BargLabs/cejel on GitHub.

You'll find Cejel in the Development category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below.
