Capability Broker
for AI Agents
Policy engine, approval flows, and audit trail for any agent runtime. Give your agents the right tools — and nothing more.
AI agents can call any tool, access any file, and hit any API. Without a governance layer, that's a production incident waiting to happen. Outcall sits between your agent and the outside world — enforcing policy, capturing every action, and routing dangerous calls to a human approver.
How Outcall works
Every tool call flows through a policy evaluation pipeline.
5 built-in guardrails
Deny-by-default protection against the most dangerous agent behaviors.
Everything you need to govern agents
From policy evaluation to human approval to immutable audit logs.
Policy Engine
Declarative allow/deny rules per agent, tool, and environment. YAML or JSON configuration.
Approval Gates
Human-in-the-loop approvals via Web UI, Telegram, or Discord. Configurable timeouts and escalation.
Audit Trail
Immutable log of every agent action: tool called, policy decision, approval status, and timestamp.
Tool Marketplace
8 built-in executors. Compose permissions per executor. Author custom executors with typed manifests.
Human approval,
wherever you work
When an agent wants to do something risky, Outcall routes the approval request to the right channel — instantly. Approve or deny from your preferred interface.
8 built-in executors
Every executor has a typed permission manifest. Compose exactly what each agent needs.
