Oh My Pi is a free MCP server tool by Can Bölük, designed as a terminal AI coding agent for the mcp platform. Built with TypeScript for agent logic and Rust for high-performance operations like search and AST manipulation, it integrates Bun as its JavaScript runtime and Python for persistent execution. This tool equips developers with deep IDE-style capabilities directly within the terminal, connecting to numerous AI models and offering a rich set of tools for various coding tasks. It aims to empower advanced users with control over models, memory, and execution surfaces.

What does Oh My Pi connect to?

Oh My Pi connects to a variety of large language models and AI coding assistants, including Claude Code, ChatGPT, Anthropic, OpenAI, Google Gemini, and Mistral. It also supports local inference engines like Ollama and LM Studio. For code intelligence and debugging, it integrates with Language Server Protocol (LSP) and Debug Adapter Protocol (DAP). Furthermore, it connects to external MCP servers and uses Hindsight as its backend for long-term memory storage.

Core features and tools

Oh My Pi provides a suite of tools that expand on the minimal Pi framework. Key explicit tools include read to inspect files, write to create or modify files, edit for file manipulation, and bash to execute shell commands. It also features internal tools such as search and task. For MCP server interactions, it offers mcp({ connect: "server" }), /mcp reconnect <server>, and mcpScript. The system supports custom tools, with an example showing a repo_stats tool, and has over 32 built-in tools.

Who is it for?

Oh My Pi is for developers, advanced users comfortable with command-line interface tooling, and terminal-native teams. It suits those seeking an open terminal AI coding agent with IDE-level tools and direct control over AI models, memory, and execution environments. This audience values deep integration and automation within their development workflow. Skip this if you prefer graphical user interfaces exclusively and are not comfortable with command-line interactions.

How to get started

The server authenticates using an API key passed as an environment variable, such as AIMLAPI_API_KEY, which Oh My Pi automatically discovers. Access for MCP servers is granted through a standard OAuth authorization flow.

Use cases

• Code Refactoring and Editing: It enables structural code changes and refactoring through hash-anchored edits and LSP integration, ensuring syntactically valid and reliable modifications across files and projects.
• Debugging and Problem Diagnosis: It can attach real debuggers (e.g., lldb, dlv, debugpy) to running processes via DAP, allowing it to set breakpoints, step through execution, inspect stack frames, and evaluate live variable states to diagnose runtime bugs.
• Automated Development Pipelines: Through its RPC mode and subagent architecture, it supports fanning out tasks into isolated worktrees and automating workflows, enabling structured, schema-validated results for continuous integration and deployment scenarios.

Oh My Pi, by Can Bölük, provides a powerful terminal AI coding agent that deeply integrates with various AI models and developer protocols. Its architecture, combining TypeScript and Rust, delivers both logical flexibility and performance. With a rich set of tools and support for key development workflows, it positions itself as a capable solution for terminal-oriented development. It caters to those who need fine-grained control over their AI-powered coding environment.
