Agent Builder

Guidance for configuring a target n8n agent's build configuration. Each area below has a dedicated reference file with the full operating procedure. Match the user's request to the area, then load that reference with load_skill({ skillId: "agent-builder", filePath: "references/<file>.md" }) before acting — do not act on an area from memory.

Tools

All builder actions run through a single agent_builder tool. Invoke an action as agent_builder({ action: "<name>", ...args }). Available actions: create_agent, read_config, build_agent, search_nodes, get_node_types, get_resource_locator_options, create_skill, create_task, build_custom_tool, list_integration_types, list_sub_agents, list_agents, list_workflows, search_mcp_servers, verify_mcp_server, resolve_llm.

Credentials are listed via the native credentials tool (not an agent_builder action) — call credentials({ action: "list", type?, name? }).
