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