  Tool(
      name="switch_replace",
      description=(
          "Replace the instruction at an offset from main with a new instruction. "
          "Offset and instruction are both hex values."
      ),
      inputSchema=ReplaceArgs.model_json_schema(),
  ),

• src/gdb_multiarch_mcp/server.py:178-183 (schema)

  Input schema definition for the switch_replace tool.
