"Firewalla" matching MCP servers:

MCP server that exposes high-level tooling for Cisco Secure Firewall Management Center (FMC), allowing discovery of FMC profiles and searching access rules by IP, FQDN, or identity indicators.

A local MCP server that acts as a policy-based firewall for personal context, letting users control agent access to their data with deny-by-default rules, per-field grants, and an audit trail.

Enables autonomous AI agents and MCP-compliant clients to detect and block adversarial prompt injections, jailbreak attempts, system prompt exfiltration, and tool hijacking via a zero-dependency, sub-millisecond heuristic firewall.
