The Auth0 MCP server exposes 10 write tools alongside 10 read tools. Write operations carry risk of unintended bulk modifications.
Write operations (auth0_create_action, auth0_create_application, auth0_create_application_grant) modify state. Without rate limits, an agent can make hundreds of changes in seconds -- faster than any human can review or revert.
Execute tools (auth0_deploy_action) trigger processes with side effects. Builds, notifications, workflows -- all fired without throttling.
These Auth0 tools can modify, create, or destroy resources. Without a policy, your agent has unrestricted access to all of them.
auth0_create_action Create a new Auth0 action Write auth0_create_application Create a new Auth0 application Write auth0_create_application_grant Create a client grant for API access Write auth0_create_form Create a new Auth0 form Write auth0_create_resource_server Create a new Auth0 resource server (API) Write auth0_publish_form Publish an Auth0 form Write auth0_update_action Update an Auth0 action Write auth0_update_application Update an Auth0 application Write auth0_update_form Update an Auth0 form Write auth0_update_resource_server Update an Auth0 resource server Write auth0_deploy_action Deploy an Auth0 action to production Execute These rules are based on the tool categories exposed by the Auth0 MCP server. Adjust the limits to match your use case.
auth0_create_action:
rules:
- name: "write-rate-limit"
rate_limit: 30/hour
on_deny: "Write rate limit reached" Prevents bulk unintended modifications from agents caught in loops.
auth0_get_action:
rules:
- action: allow
rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
This is the complete policy file for Auth0. It lists every tool with suggested default rules. Download it, adjust the limits, and run with Intercept.

Download the policy
curl -o auth0.yaml https://raw.githubusercontent.com/policylayer/intercept/main/policies/auth0.yaml
Run Intercept in front of the server
intercept -c auth0.yaml -- npx -y @@@auth0/auth0-mcp-server
Works with any MCP client:
Every tool call is now checked against your policy before it reaches Auth0. Denied calls are blocked and logged. Allowed calls pass through with no latency impact.
Open source. One binary. Zero dependencies.
