MCP Output Firewall

Verified · 2 mo ago

Three-layer firewall for MCP: content, egress and action policy. Proxy or server.

Install

claude mcp add mcp-output-firewall -- npx -y [email protected]

Our take

Implements an MCP firewall covering content, egress, and action policy, usable as either a proxy or server. It is for developers trying to add policy controls around MCP tool output, and the npm package is a useful maturity signal, though zero stars suggest it still needs careful security review before trust-sensitive deployment.
