Write operations (unlock_financial_analysis) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.
unlock_financial_analysis:
rules:
- rate_limit: 30/hour Prevents bulk unintended modifications from agents caught in loops.
stock_data_query:
rules:
- rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
The Shibui Finance server has 1 write tools including unlock_financial_analysis. 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.
2 tools across 2 categories: Read, Write. 1 are read-only. 1 can modify, create, or delete data.
One line change. Instead of running the Shibui Finance server directly, prefix it with Intercept: intercept -c shibui-finance.yaml -- npx -y @shibui/finance. Download a pre-built policy from policylayer.com/policies/shibui-finance and adjust the limits to match your use case.
