Every agent tool call gets a verdict before it runs

Capability-scoped authority for every agent and tool call. Each call is evaluated against policy before it executes, with authority revoked when behavior drifts.

The threats

Agents act. That changes the threat model

When an agent can post to a ledger, query a database, or email a customer, a bad decision is no longer a bad answer. It’s an action. Least privilege has to be enforced at the moment of the call.

Excessive agency

An agent with broad tool access takes actions far beyond its intended scope: moving money, deleting records, emailing customers.

Injection-driven tool abuse

A poisoned document or prompt hijacks the agent and turns its legitimate tools into the attacker’s: exfiltration, fraud, sabotage.

Confused-deputy escalation

A low-trust input coerces a high-privilege agent into acting on its behalf, crossing trust boundaries it was never meant to bridge.

Destructive actions

One unchecked call (db.drop_table, a bulk delete, an irreversible transfer) and there’s no undo and no record of who decided.

Data exfiltration via tools

Agents read sensitive data, then leak it through a tool call, an API request, or a crafted link. No human ever sees it leave.

Untrusted MCP & tools

Connected agents pull in third-party and MCP tools with their own permissions: a supply chain you didn’t vet acting in your name.

Capability scoping

Least privilege, enforced per call

Grant each agent only the tools and data it needs. Every call is checked against its capability grants before it runs. Anything out of scope is refused, not logged after the fact.

  • Fine-grained scopes per agent and tool
  • Intent & context checks, not static allow-lists
  • First-class support for MCP & connected agents

Tool-call gateway

One chokepoint in front of every tool

However many agents you run, every tool and MCP call funnels through a single gateway that evaluates it against policy. No agent talks to a sensitive tool directly.

Drift & revocation

Authority that ends the moment behavior does

Agents earn authority for a task, not forever. When behavior deviates from the expected pattern mid-session, Intercept revokes the grant and signs the revocation.

  • Instant, mid-session revocation
  • Every revocation written to the evidence ledger

How it works

From tool call to verdict to receipt

01

Intercept

The agent’s tool call is captured at the gateway before execution.

02

Evaluate

Capability grants, rate limits, intent, and context are checked against policy.

03

Enforce

Allow and execute, or block and revoke, in single-digit milliseconds.

04

Sign

The verdict and full context are signed into the evidence ledger.

Standards

Built on open identity and policy standards
