Platform Overview

The sidclawhq/platform MCP server wraps upstream MCP servers and evaluates each tool call against configured policies. It can allow actions immediately, block them, or pause them for human approval before execution, while recording decisions in hash-chained audit trails. Use it when an MCP client needs oversight for high-risk operations such as infrastructure changes, messages, or sensitive workflows. The proxy works with MCP clients including Claude Desktop and Cursor.
