What it is
Agent identity validation is the process of verifying that a request genuinely comes from a known, registered agent and that the agent is authorized to take the action it's attempting. Without it, any process can impersonate any agent.
Each agent in production should have a declared identity: agent ID, authorized tools (allowed_tools list), rate limit (max requests per minute), and other metadata. When an agent attempts to use a tool, the governance system verifies: is this agent registered? Is it attempting to use a tool it's allowed to use? Is it within its rate limit?
Why it matters
This is OWASP Agentic AI Threat T9: Identity Spoofing. Without identity validation, an attacker who gains access to the system could spin up a rogue process that looks like agent-trading-bot and use it to trade unauthorized positions. Or a compromised agent could request expanded tool access.
Identity validation also enables per-agent rate limits and tool scoping. Agent A (compliance checker) can only use read_database and send_email. Agent B (incident responder) can use terminate_process and restart_service. This prevents lateral movement — a compromised agent can't access tools it was never authorized for.
How it works
Before executing any tool call, the proxy verifies: agent provides an ID → lookup in registry → confirm ID exists → confirm requested tool is in agent's allowed_tools list → confirm rate limit not exceeded. If any check fails, the action is denied.
The agent registry is maintained by your operations team and is queryable by the proxy. It's the source of truth for what each agent is allowed to do.
How Intercis implements it
Intercis maintains an agent registry where you define each agent: ID, human-readable name, allowed_tools (list of tool names), rate_limit_rpm (requests per minute), and tags. When the proxy intercepts a tool call, it validates:
- Agent ID is known (exists in registry)
- Agent is active (not suspended or revoked)
- Requested tool is in agent's allowed_tools list
- Agent has not exceeded its rate limit
If validation fails, the action is denied and logged. You can update the registry without redeploying agents, allowing you to add new agents, revoke compromised ones, or adjust tool scopes on-the-fly.
