Financial operations (transfer_tokens) can move real money. An agent caught in a loop could drain accounts before anyone notices.
Destructive tools (burn_tokens) permanently delete resources. There is no undo. An agent calling these in a retry loop causes irreversible damage.
Execute tools (deploy_token, estimate_cost) trigger processes with side effects. Builds, notifications, workflows — all fired without throttling.

Yes. The Token Tool server exposes 1 financial tools including transfer_tokens. Without a policy, an autonomous agent can call these with no spend caps, no rate limits, and no approval flow. PolicyLayer lets you block financial tools by default, require human approval, or set per-tool rate limits — enforced on every call.
Yes. The Token Tool server exposes 1 destructive tools including burn_tokens. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.
11 tools across 4 categories: Destructive, Execute, Financial, Read. 7 are read-only. 4 can modify, create, or delete data.
Register the Token Tool MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.
Starter policies for each. Same risk classification, live on your fleet in minutes.
Deterministic rules across all 11 Token Tool tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
