125 tools. 83 can modify or destroy data without limits.
3 destructive tools with no built-in limits. Policy required.
Last updated:
Destructive tools (remove_intent_card, revoke_delegation, revoke_endorsement) permanently delete resources. There is no undo. An agent calling these in a retry loop causes irreversible damage.
Write operations (accept_assignment, activate_emergency, add_approval_signature) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.
Execute tools (commerce_preflight, execute_with_context, gateway_execute_approval) trigger processes with side effects. Builds, notifications, workflows — all fired without throttling.
Intercept sits between your agent and Agent Passport System — Cryptographic Identity for AI Agents. Every tool call checked against your policy before it executes — so your agent can do its job without breaking things.
npx -y @policylayer/intercept scan -- npx -y @agent-passport-system-mcp remove_intent_card:
rules:
- action: deny Destructive tools should never be available to autonomous agents without human approval.
accept_assignment:
rules:
- rate_limit: 30/hour Prevents bulk unintended modifications from agents caught in loops.
check_aggregate_constraints:
rules:
- rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
Yes. The Agent Passport System — Cryptographic Identity for AI Agents server exposes 3 destructive tools including remove_intent_card, revoke_delegation, revoke_endorsement. These permanently remove resources with no undo. Intercept blocks destructive tools by default so they never reach the upstream server.
The Agent Passport System — Cryptographic Identity for AI Agents server has 75 write tools including accept_assignment, activate_emergency, add_approval_signature. Set rate limits in your policy file -- for example, rate_limit: 10/hour prevents an agent from making more than 10 modifications per hour. Intercept enforces this at the transport layer.
125 tools across 4 categories: Destructive, Execute, Read, Write. 42 are read-only. 83 can modify, create, or delete data.
One line change. Instead of running the Agent Passport System — Cryptographic Identity for AI Agents server directly, prefix it with Intercept: intercept -c agent-passport-system-cryptographic-identity-for-ai-agents.yaml -- npx -y @agent-passport-system-mcp. Download a pre-built policy from policylayer.com/policies/agent-passport-system-cryptographic-identity-for-ai-agents and adjust the limits to match your use case.
Starter policies available for each. Same risk classification, same one-command setup.
Set budgets, approvals, and hard limits across MCP servers.
