Destructive tools (agent__remove_dependency, aithroyz_destroy_tenant, delete_mcp_connection) permanently delete resources. There is no undo. An agent calling these in a retry loop causes irreversible damage.

Write operations (activate_mcp, add_mcp_connection, agent__activate) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.

Execute tools (aithroyz_provision_tenant, call_mcp_tool, vault_sync) trigger processes with side effects. Builds, notifications, workflows — all fired without throttling.

One command. Full control.

Intercept sits between your agent and Clevername. Every tool call checked against your policy before it executes — so your agent can do its job without breaking things.

Deny destructive operations
agent__remove_dependency:
  rules:
    - action: deny

Destructive tools should never be available to autonomous agents without human approval.

Rate limit write operations
activate_mcp:
  rules:
    - rate_limit: 30/hour

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations
agent__list_departments:
  rules:
    - rate_limit: 60/minute

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Can an AI agent delete data through the Clevername MCP server? +

Yes. The Clevername server exposes 10 destructive tools including agent__remove_dependency, aithroyz_destroy_tenant, delete_mcp_connection. These permanently remove resources with no undo. Intercept blocks destructive tools by default so they never reach the upstream server.

How do I prevent bulk modifications through Clevername? +

The Clevername server has 16 write tools including activate_mcp, add_mcp_connection, agent__activate. 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.

How many tools does the Clevername MCP server expose? +

67 tools across 4 categories: Destructive, Execute, Read, Write. 38 are read-only. 29 can modify, create, or delete data.

How do I add Intercept to my Clevername setup? +

One line change. Instead of running the Clevername server directly, prefix it with Intercept: intercept -c clevername.yaml -- npx -y @@clevername/clevername-mcp. Download a pre-built policy from policylayer.com/policies/clevername and adjust the limits to match your use case.
