Implementation Reference

• complete_fastmcp_server.py:304-327 (handler)

  The primary handler function for the MCP tool 'run_ecs_command'. Registered via @app.tool(). It wraps and calls the underlying OOS_RunCommand by dynamic lookup.

• alibaba_cloud_ops_mcp_server/tools/oos_tools.py:49-54 (schema)

  Pydantic-based input schema definitions for the OOS_RunCommand function, which defines parameters like Command, InstanceIds, RegionId, and CommandType.

• alibaba_cloud_ops_mcp_server/tools/oos_tools.py:48-72 (handler)

  Core handler implementation OOS_RunCommand that invokes Alibaba Cloud OOS to run commands on multiple ECS instances using the 'ACS-ECS-BulkyRunCommand' template.
