Financial operations (calculate_reverse_charge) can move real money. An agent caught in a loop could drain accounts before anyone notices.
Intercept sits between your agent and Sg Gst Calculator. Every tool call checked against your policy before it executes — so your agent can do its job without breaking things.

Yes. The Sg Gst Calculator server exposes 1 financial tools including calculate_reverse_charge. 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.
4 tools across 2 categories: Financial, Read. 3 are read-only. 1 can modify, create, or delete data.
One line change. Instead of running the Sg Gst Calculator server directly, prefix it with Intercept: intercept -c vdineshk-sg-gst-calculator-mcp.yaml -- npx -y @vdineshk/sg-gst-calculator-mcp. Download a pre-built policy from policylayer.com/policies/vdineshk-sg-gst-calculator-mcp 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.
