See [CLI Tools](https://docs.hatch3r.com/docs/getting-started/cli-tools) for the full 29-tool table and the trade-off discussion vs MCP. ## MCP Configuration Since 1.7.5, MCP is **opt-in**; since 2.0.0 interactive `npx hatch3r init` no longer offers an MCP prompt. Without an opt-in, init skips MCP entirely -- no `.env.mcp`, no `mcp.json`, no servers in the manifest, and `features.mcp` stays false. When you opt in (`init --mcp` on any init path, or `npx hatch3r mcp setup` afterwards), hatch3r writes a gitignored `.env.mcp` with the required environment variables and MCP config to the tool-appropriate location (`.cursor/mcp.json`, `.mcp.json`, `.vscode/mcp.json`). - **VS Code / Copilot:** secrets pass via the `env` object in `.vscode/mcp.json`. - **Cursor / Claude Code / others:** source the file first: `set -a && source .env.mcp && set +a && cursor .` Manage MCP at any time via `npx hatch3r mcp setup
