This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start: AGENTS_DIR (Absolute path to the directory containing agent definition files (.md or .txt)), AGENT_TYPE (Type of AI CLI to use: 'cursor', 'claude', 'gemini', 'codex', 'command-code', 'glm', 'kimi', 'grok', 'antigravity', or 'opencode'), AGENT_PERMISSION (Approval/sandbox level for sub-agents: 'read-only', 'safe-edit' (default), or 'yolo'), AGENT_MODEL (Optional model override applied to every sub-agent execution by this MCP server), AGENT_EFFORT (Optional backend-specific reasoning effort or model variant. Supported by codex, claude, command-code, glm, kimi, grok, antigravity, and opencode.), CURSOR_API_KEY (API key for cursor-agent authentication (used only when AGENT_TYPE=cursor; passed via env, never via CLI args)), CLI_API_KEY (Provider API key for AGENT_TYPE=glm or kimi (passed to the claude binary via env, never via CLI args). Restart/reconnect the MCP server after changing it.), EXECUTION_TIMEOUT_MS (Agent execution timeout in milliseconds, as a positive whole number (default: 300000). The server refuses to start on an invalid value such as "5min".), SESSION_ENABLED (Enable session management to maintain execution history across agent calls (default: false)), SESSION_DIR (Directory path for storing session files (default: .mcp-sessions in current working directory)), SESSION_RETENTION_DAYS (Number of days to retain session history before automatic cleanup (default: 1)), AGENTS_SETTINGS_PATH (Path to CLI settings file/directory. Claude: --settings arg, Cursor: CURSOR_CONFIG_DIR, Codex: CODEX_HOME. GLM/Kimi/Gemini/Grok/Antigravity/OpenCode/Command Code not supported.). The author declared them in the registry entry; get the values from the project itself.
