arc-gate-mcp
Runtime governance proxy for MCP tool calls. Blocks prompt injection and capability abuse before tool results reach your agent.
What it does
arc-gate-mcp sits between your MCP client and any MCP server. Every tool result passes through Arc Gate governance before reaching your agent — blocking prompt injection attacks that exploit the MCP trust boundary.
