16 tools. 7 can modify or destroy data without limits.
1 destructive tool with no built-in limits. Policy required.

Financial operations (grid_pay) can move real money. An agent caught in a loop could drain accounts before anyone notices.
Write operations (grid_counter, grid_register, grid_send_message) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.
Execute tools (grid_inquire, grid_rate) trigger processes with side effects. Builds, notifications, workflows — all fired without throttling.
grid_pay:
rules:
- action: deny Financial tools should be explicitly enabled per use case, not open by default.
grid_counter:
rules:
- rate_limit: 30/hour Prevents bulk unintended modifications from agents caught in loops.
grid_accept_deal:
rules:
- rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
Yes. The GRID server exposes 1 financial tools including grid_pay. Without a policy, an autonomous agent can call these with no spend caps, no rate limits, and no approval flow. Intercept lets you block financial tools by default or set per-tool rate limits.
The GRID server has 4 write tools including grid_counter, grid_register, grid_send_message. 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.
16 tools across 4 categories: Execute, Financial, Read, Write. 9 are read-only. 7 can modify, create, or delete data.
One line change. Instead of running the GRID server directly, prefix it with Intercept: intercept -c travisanthonygerber-grid.yaml -- npx -y @travisanthonygerber/GRID. Download a pre-built policy from policylayer.com/policies/travisanthonygerber-grid and adjust the limits to match your use case.
Starter policies available for each. Same risk classification, same one-command setup.
