What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

этот файл ставится пользователю, но в репозитории его нет

    result = subprocess.run(

        path = os.path.join(root, rel)

    child = spawn(command, childArgs, { cwd: DIR, env: childEnv(), stdio: "inherit" });

        base_env=dict(os.environ),

        size = sum(os.path.getsize(os.path.join(r, f)) for r, _, fs in os.walk(out) for f in fs)

Optional settings from the registry entry, left out of the block above: ANTHROPIC_API_KEY (Provider key for codna_fix's planner — any one of ANTHROPIC_API_KEY (Anthropic), OPENAI_API_KEY (OpenAI/ChatGPT), or GEMINI_API_KEY (Gemini) works (or store one with `codna key set <provider>`). Every tool also requires the one-time free `codna login` device authorization before executing; introspection (initialize/tools/list) needs no credentials), OPENAI_API_KEY (Alternative provider key (OpenAI/ChatGPT) for codna_fix's planner — see ANTHROPIC_API_KEY), GEMINI_API_KEY (Alternative provider key (Gemini) for codna_fix's planner — see ANTHROPIC_API_KEY), GITHUB_TOKEN (Write token, only for codna_fix with open_pr=true (opens a pull request) and codna_report_bug (files an issue)), CODNA_API_KEY (Codna key from the one-time free `codna login` (device authorization, free community license). Required to execute any of the five tools; introspection (initialize/tools/list) needs none).
