Zero-egress AI Agent Firewall: SARA prompt injection defense, AST context pruning & MCP governance.

Install

claude mcp add ctxfw -- uvx ctxfw

Our take

ctxfw provides a locally operated agent firewall with prompt-injection defenses, context pruning, and MCP governance controls. It targets teams running security-sensitive agent workflows, though its low adoption signal and broad security claims warrant careful validation before relying on it as a primary control.
