The micro mcp test command was documented in help text and examples but returned a "not yet implemented" placeholder.

Changes

• cmd/micro/mcp/mcp.go: Implemented testAction to:

  • Parse tool names (service.endpoint or service.Handler.Method formats)
  • Discover services from registry
  • Make RPC calls using bytes codec for raw JSON payloads
  • Pretty-print responses with proper error handling

• cmd/micro/mcp/mcp_test.go: Added unit tests for tool name parsing

Usage

# Test with empty input
micro mcp test greeter.Greeter.Hello

# Test with JSON payload
micro mcp test greeter.Greeter.Hello '{"name":"World"}'

Output shows service/endpoint details, validates JSON input, and displays formatted responses or error messages.
