What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs on your computer
Transport: stdio
Category: Developer tools

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
The registry lists no key to fill in.

You need

npmNode.js installed (for the npx command)

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "my-pi": {
      "command": "npx",
      "args": [
        "-y",
        "@koonwang03/my-pi",
        "--workspace",
        "your-value"
      ]
    }
  }
}

Run this in your terminal

claude mcp add my-pi -- npx -y @koonwang03/my-pi --workspace your-value

This one needs values on its command line, so copy the settings and fill them in.

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "my-pi": {
      "command": "npx",
      "args": [
        "-y",
        "@koonwang03/my-pi",
        "--workspace",
        "your-value"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Common questions

Is my-pi safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0-alpha.2) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

my-pi

my-pi is a local-first Model Context Protocol (MCP) runtime for coding agents that need controlled access to a real codebase without handing the agent an unrestricted shell.

It combines bounded filesystem operations, content-preconditioned writes, structural AST search, language-server navigation, Git status/diff tooling, and an explicit read-only-by-default security model behind one stdio MCP server.

Why my-pi

Local-first: source code and detailed workspace state stay on the host.
Read-only by default: mutation and language-server process startup require explicit elevation.
Safer writes: updates can be guarded by content fingerprints instead of blind overwrites.
Code-aware navigation: Tree-Sitter AST search plus LSP symbols, definitions, references, hover, and diagnostics.
Git-aware context: bounded status and diff capabilities without exposing an unrestricted command runner.
Host-neutral: designed for MCP-capable coding environments including Claude Code, Cursor, and OpenCode.

Install and run

Requires Node.js >=24.0.0.

npm install -g @koonwang03/my-pi

my-pi-mcp --workspace /path/to/project

Or inspect a generated host configuration without a global install:

npx --yes --package @koonwang03/my-pi my-pi-mcp host-config cursor-local

The server starts in the read-only security profile. Enable writes and language-server processes only for a trusted workspace:

my-pi-mcp --workspace /path/to/project --security-profile trusted

Starting without --workspace or MY_PI_WORKSPACE_ROOT fails closed. Use --allow-cwd only as an intentional opt-in to the current directory.

Core MCP capabilities

The stable alpha surface exposes 13 tools across four groups:

Filesystem: fs_read, fs_write, fs_patch, fs_stat
Search/workspace: search, workspace_info
AST/LSP: ast_search, lsp_status, lsp_symbols, lsp_navigate, lsp_diagnostics
Git: vcs_status, vcs_diff

Structural AST search supports TypeScript, JavaScript, Python, Rust, and Go. LSP integrations support TypeScript, Python, Rust, and Go when compatible language-server executables are available on the host.

Generate host configuration

my-pi-mcp host-config claude-code-local

my-pi-mcp host-config cursor-local my-pi-mcp host-config opencode-current-local

Security model

my-pi uses explicit workspace authority and pre-read sensitive-path policy. The default profile is intentionally restrictive; trusted mode is an explicit opt-in for mutation and language-server processes.

Review the full security model before enabling trusted mode:

https://github.com/BoxBoxmari/my-pi/blob/main/docs/SECURITY_MODEL.md

Project status

Current release channel: alpha. The package is intended for evaluation and controlled local development while coordination/evaluation features under the repository's "Production Next" work remain experimental.

The primary executable is my-pi-mcp; ccr-mcp is retained as a compatibility alias.
