Fidacy - Authority Firewall for AI Agents
by•
Fidacy is the layer that lets AI agents scale safely and without fear. Every agent action is checked against a signed mandate before it runs, and every decision becomes a receipt anyone can verify offline. It runs as an MCP server, so you can install it right now with a single line.

Hi Product Hunt! I'm Lucas, founder of Fidacy.
AI agents can now pay suppliers, issue refunds, delete files and change production. The problem is that most teams only control them with prompts and dashboards, which advise but don't stop anything. One hijacked or confused agent can do real damage with access you already gave it.
Fidacy is the layer that lets AI agents scale safely and without fear. Before any consequential action runs, Fidacy checks it against a signed mandate. If the action isn't allowed, it's blocked. Every decision becomes a receipt anyone can verify offline, so security teams, auditors and insurers don't have to take anyone's word for it.
You can block an agent in one click, open an incident pack, unblock a single action when it's safe, and see trend reports on what your agents are trying to do.
It runs as an MCP server, so you can install it in Claude, Cursor, Codex and other agents with a single line. Our connectors already passed 44,000 downloads, and 1,597 agents run with Fidacy today.
We're live in production and part of NVIDIA Acceleration Program. I'd love your feedback, especially on the one action you'd never let an agent take without a signed yes.
