Write operations (accounts.contacts.create, accounts.create, accounts.search) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.
Intercept sits between your agent and Exact Online. 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 @IndustrialIT/LedgerBotje accounts.contacts.create:
rules:
- rate_limit: 30/hour Prevents bulk unintended modifications from agents caught in loops.
admin.feedback:
rules:
- rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
The Exact Online server has 12 write tools including accounts.contacts.create, accounts.create, accounts.search. 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.
50 tools across 2 categories: Read, Write. 38 are read-only. 12 can modify, create, or delete data.
One line change. Instead of running the Exact Online server directly, prefix it with Intercept: intercept -c industrialit-ledgerbotje.yaml -- npx -y @IndustrialIT/LedgerBotje. Download a pre-built policy from policylayer.com/policies/industrialit-ledgerbotje and adjust the limits to match your use case.
Set budgets, approvals, and hard limits across MCP servers.
