25 tools. 14 can modify or destroy data without limits.
3 destructive tools with no built-in limits. Policy required.

Financial operations (printr_transfer) can move real money. An agent caught in a loop could drain accounts before anyone notices.
Destructive tools (printr_wallet_bulk_remove, printr_wallet_remove) permanently delete resources. There is no undo. An agent calling these in a retry loop causes irreversible damage.
Write operations (printr_create_token, printr_open_web_signer, printr_set_treasury_wallet) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.
Execute tools (printr_drain_deployment_wallet, printr_fund_deployment_wallet, printr_launch_token) trigger processes with side effects. Builds, notifications, workflows — all fired without throttling.
printr_transfer:
rules:
- action: deny Financial tools should be explicitly enabled per use case, not open by default.
printr_wallet_bulk_remove:
rules:
- action: deny Destructive tools should never be available to autonomous agents without human approval.
printr_create_token:
rules:
- rate_limit: 30/hour Prevents bulk unintended modifications from agents caught in loops.
printr_claim_fees:
rules:
- rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
Yes. The Printr server exposes 1 financial tools including printr_transfer. 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.
Yes. The Printr server exposes 2 destructive tools including printr_wallet_bulk_remove, printr_wallet_remove. These permanently remove resources with no undo. Intercept blocks destructive tools by default so they never reach the upstream server.
The Printr server has 7 write tools including printr_create_token, printr_open_web_signer, printr_set_treasury_wallet. 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.
25 tools across 5 categories: Destructive, Execute, Financial, Read, Write. 11 are read-only. 14 can modify, create, or delete data.
One line change. Instead of running the Printr server directly, prefix it with Intercept: intercept -c io-github-printrfi-printr.yaml -- npx -y @@printr/mcp. Download a pre-built policy from policylayer.com/policies/io-github-printrfi-printr and adjust the limits to match your use case.
Starter policies available for each. Same risk classification, same one-command setup.
