4 write tools that can modify data. Rate limits recommended.

Execute tools (build, compose-build, exec) trigger processes with side effects. Builds, notifications, workflows — all fired without throttling.
Intercept sits between your agent and Docker. Every tool call checked against your policy before it executes — so your agent can do its job without breaking things.

rules:
- rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
The Docker server is primarily read-only with 12 read tools. While it cannot modify data, an agent in a retry loop can make thousands of API calls per minute, exhausting rate limits and running up costs. Rate limiting is still recommended.
16 tools across 2 categories: Execute, Read. 12 are read-only. 4 can modify, create, or delete data.
One line change. Instead of running the Docker server directly, prefix it with Intercept: intercept -c io-github-dave-london-docker.yaml -- npx -y @@paretools/docker. Download a pre-built policy from policylayer.com/policies/io-github-dave-london-docker 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.
