19 tools. 9 can modify or destroy data without limits.
1 destructive tool with no built-in limits. Policy required.
Last updated:
Destructive tools (change-extension-installation) permanently delete resources. There is no undo. An agent calling these in a retry loop causes irreversible damage.
Write operations (create-new-project, manage-env-vars, manage-form-submissions) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.
Execute tools (deploy-site, initialize-database) trigger processes with side effects. Builds, notifications, workflows — all fired without throttling.
Intercept sits between your agent and Netlify. Every tool call checked against your policy before it executes — so your agent can do its job without breaking things.

Yes. The Netlify server exposes 1 destructive tools including change-extension-installation. These permanently remove resources with no undo. Intercept blocks destructive tools by default so they never reach the upstream server.
The Netlify server has 6 write tools including create-new-project, manage-env-vars, manage-form-submissions. 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.
19 tools across 4 categories: Destructive, Execute, Read, Write. 10 are read-only. 9 can modify, create, or delete data.
One line change. Instead of running the Netlify server directly, prefix it with Intercept: intercept -c netlify.yaml -- npx -y @@@netlify/mcp. Download a pre-built policy from policylayer.com/policies/netlify and adjust the limits to match your use case.
Starter policies available for each. Same risk classification, same one-command setup.
