Arc Gate MCP Overview

9hannahnine-jpg/arc-gate-mcp MCP server sits between an MCP client and an upstream MCP server, inspecting tool results before they reach the agent. It applies governance policies intended to block prompt injection and capability abuse at the MCP trust boundary. Choose from general-purpose, browser, finance, retrieval, or strict enforcement modes. Reach for it when an agent needs an additional runtime control layer around an existing MCP server.
