19 tools. 7 can modify or destroy data without limits.
5 destructive tools with no built-in limits. Policy required.

Financial operations (build_deposit_tx, build_queue_withdraw_tx, build_redeem_withdraw_tx) can move real money. An agent caught in a loop could drain accounts before anyone notices.
Execute tools (build_stake_tx, build_unstake_tx) trigger processes with side effects. Builds, notifications, workflows — all fired without throttling.
Intercept sits between your agent and Atv. 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 @aarna-ai/atv build_deposit_tx:

get_deposit_status:

- rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
Yes. The Atv server exposes 5 financial tools including build_deposit_tx, build_queue_withdraw_tx, build_redeem_withdraw_tx. 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.
19 tools across 3 categories: Execute, Financial, Read. 12 are read-only. 7 can modify, create, or delete data.
One line change. Instead of running the Atv server directly, prefix it with Intercept: intercept -c aarna-ai-atv.yaml -- npx -y @aarna-ai/atv. Download a pre-built policy from policylayer.com/policies/aarna-ai-atv 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.
