Installation¶

Prerequisites¶

MCP server setup (recommended)¶

The fastest way to start using Zen of Languages is to add the MCP server to your editor or AI assistant. No global install required — uvx runs the server in an isolated environment.

Claude Desktop¶

Add to claude_desktop_config.json (usually ~/Library/Application Support/Claude/ on macOS or %APPDATA%\Claude\ on Windows):

{
  "mcpServers": {
    "zen-of-languages": {
      "command": "uvx",
      "args": ["--from", "mcp-zen-of-languages", "mcp-zen-of-languages-server"]
    }
  }
}

VS Code¶

Add to .vscode/mcp.json in your workspace, or use one of the one-click install badges below:

{
  "servers": {
    "zen-of-languages": {
      "command": "uvx",
      "args": ["--from", "mcp-zen-of-languages", "mcp-zen-of-languages-server"]
    }
  }
}

Method	VS Code	VS Code Insiders
UVX (native)
Docker (isolated)

Cursor / Windsurf¶

Add to .cursor/mcp.json or .windsurf/mcp.json in your project root:

{
  "mcpServers": {
    "zen-of-languages": {
      "command": "uvx",
      "args": ["--from", "mcp-zen-of-languages", "mcp-zen-of-languages-server"]
    }
  }
}

Codex¶

Add to ~/.codex/config.toml:

[mcp_servers."zen-of-languages"]
command = "uvx"
args = ["--from", "mcp-zen-of-languages", "mcp-zen-of-languages-server"]
enabled = true

Codex reads MCP servers from the global ~/.codex/config.toml file rather than a workspace .json file. If you want to pin a config file, add env = { ZEN_CONFIG_PATH = "/absolute/path/to/zen-config.yaml" } under the same table.

Claude Code¶

Install via the CLI:

claude mcp add zen-of-languages -- uvx --from mcp-zen-of-languages mcp-zen-of-languages-server

For the full integration guide — including environment variables, debugging, and troubleshooting — see MCP Integration.

Install with Docker (no local Python)¶

# MCP server via Docker (default entrypoint)
docker run --rm -i ghcr.io/anselmoo/mcp-zen-of-languages:latest

# CLI via Docker
docker run --rm ghcr.io/anselmoo/mcp-zen-of-languages:latest mcp-zen-of-languages-cli --help

This image defaults to mcp-zen-of-languages-server.

Official Docker image policy¶

1. Publish a GHCR image on each vX.Y.Z release tag.
2. Keep Docker tags as latest and <major>.<minor> channels only.
3. Patch releases overwrite the same <major>.<minor> image channel.
4. Add CI smoke checks for CLI and MCP server startup in the image pipeline.

CLI — First Code Anamnesis & Local Development¶

The CLI is a powerful tool for first code anamnesis — an initial diagnostic sweep of any codebase. Use it to get a full-project health picture before wiring up MCP, or for local analysis, CI pipelines, and contributing to the project.

Run without installing¶

# Run the CLI directly
uvx --from mcp-zen-of-languages mcp-zen-of-languages-cli --help
uvx --from mcp-zen-of-languages mcp-zen-of-languages-cli init
uvx --from mcp-zen-of-languages mcp-zen-of-languages-cli reports path/to/project

# Start the MCP server
uvx --from mcp-zen-of-languages mcp-zen-of-languages-server

This is the standard approach for MCP tools and requires no setup beyond having uv installed.

Install from PyPI¶

For persistent installation:

pip install mcp-zen-of-languages

After install, the package-style commands are:

• mcp-zen-of-languages-cli — CLI for analysis, reports, and prompt generation
• mcp-zen-of-languages / mcp-zen-of-languages-server — MCP server entry points for AI agent integration

Legacy aliases remain available: zen and zen-mcp-server.

Install from source (development)¶

git clone https://github.com/Anselmoo/mcp-zen-of-languages.git
cd mcp-zen-of-languages
uv sync --group dev --group docs

This installs all development dependencies (pytest, ruff, ty) and documentation tooling (Zensical).

Verify installation¶

mcp-zen-of-languages-cli --version
mcp-zen-of-languages-cli --help

You should see the CLI help output listing init, check, report, and prompts subcommands.
