Kaimon.jlOpening the gate between AI and Julia

Expose Julia REPLs as MCP servers, enabling AI agents like Claude Code and Cursor to execute code, introspect types, run tests, debug, and search your codebase interactively.

Get Started

Tool Catalog

GitHub

MCP Server

Full Model Context Protocol implementation over stdio and SSE transports, compatible with Claude Code, Cursor, and any MCP-capable client.

32+ Tools

Code execution, type introspection, macro expansion, profiling, test running with coverage, VS Code debugging, package management, and more.

The Gate

ZMQ bridge that connects external Julia processes to the MCP server, allowing packages to register custom tools with full schema and documentation.

Terminal Dashboard

Real-time TUI built on Tachikoma.jl that monitors all connected sessions, tool calls, output streams, and server status from one terminal.

Semantic Search

Qdrant-powered vector search over your codebase. Index projects and query with natural language to find relevant functions, types, and patterns.

Security

Three security modes -- strict, relaxed, and lax -- with API key authentication and IP allowlisting to control access to your Julia sessions.

Kaimon.jl

Kaimon (開門, "opening the gate") turns any Julia REPL into a Model Context Protocol server. AI agents connect over stdio or SSE and gain full access to Julia's runtime: evaluating expressions, inspecting types, running tests, profiling code, managing packages, and searching your codebase semantically.

Quick Start

1. Install

julia

]app add Kaimon

This installs the kaimon command to ~/.julia/bin/ (make sure it's on your PATH).

2. Launch the dashboard

bash

kaimon

The first run walks you through a setup wizard (security mode, API key, port). After that, the terminal dashboard opens.

3. Connect your editor

Press i in the Config tab to install MCP config for Claude Code, Cursor, VS Code, or Gemini CLI — no manual file editing needed.

4. Connect a Julia REPL
