2 destructive tools with no built-in limits. Policy required.
Last updated:
Destructive tools (cache_stats, clear_cache) permanently delete resources. There is no undo. An agent calling these in a retry loop causes irreversible damage.
Intercept sits between your agent and SteadyFetch. Every tool call checked against your policy before it executes — so your agent can do its job without breaking things.

Yes. The SteadyFetch server exposes 2 destructive tools including cache_stats, clear_cache. These permanently remove resources with no undo. Intercept blocks destructive tools by default so they never reach the upstream server.
5 tools across 2 categories: Destructive, Read. 3 are read-only. 2 can modify, create, or delete data.
One line change. Instead of running the SteadyFetch server directly, prefix it with Intercept: intercept -c steadyfetch.yaml -- npx -y @steadyfetch. Download a pre-built policy from policylayer.com/policies/steadyfetch 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.
