# Your Auth0 tenant. Explained by your agent.

Source: https://corespeed.io/integrations/auth0

Connect Auth0 to Claude Code, Codex, Cursor or any MCP agent through CoreSpeed. Your agent manages users, roles, organizations, applications, APIs and Actions in your tenant, and reads its logs to explain a failed sign-in. It uses a Machine-to-Machine application you create, its Management API grants decide what works, and secrets are stripped from every answer.

## Set up an agent

Give your agent this line: `set up https://corespeed.io/SKILL.md (read it raw, e.g. with curl)`

It fetches the skill at https://corespeed.io/SKILL.md, adds the CoreSpeed MCP server, signs you in (or up), and keeps the skill for next time. Connect Auth0 after setup. Access follows the connected account and its permissions. Create an account: https://app.corespeed.io/sign-up

## A user cannot sign in. Find out why in one ask

Your agent finds the user, reads the tenant logs, and opens the Action behind the failure.

You ask your agent: "Reid cannot sign in since this morning. Find Reid in Auth0, read the tenant logs for the failed logins, and explain the cause. Do not change the user."

It calls CoreSpeed:

- `auth0__list_users`: ok, 362 ms
- `auth0__list_logs`: ok, 574 ms
- `auth0__get_action`: ok, 298 ms

It reads from: Auth0.

### Sign-in failure: An Action is blocking Reid.

The require-verified-email Action, deployed yesterday, denies users whose email is not verified. Reid's is not.

**Found**

- 6 failed logins since 08:12.
- Each one denied by require-verified-email.

**Options**

- Ask Reid to verify the email address.
- Or change the Action, with a review.

## Keep your agent. Bring your work

One CoreSpeed account, across compatible agents.

1. **Set up CoreSpeed**: Give your agent the setup line. It adds CoreSpeed and signs you in.
2. **Connect Auth0**: Authorize the account and the content you need.
3. **Start with one task**: Ask for a summary, a brief, or a draft. Review the answer.

## Questions

### Can my agent read client secrets?

No. CoreSpeed strips secrets and signing keys from every Auth0 answer. Get a new application's secret from the Auth0 Dashboard.

### Can my agent delete the application it connects with?

No. CoreSpeed refuses any change that names the Machine-to-Machine application the connection uses.

### Does reading logs change anything?

No. Reading is separate from writing. Creating, updating or deploying is a separate tool call, which approvals can hold for a person. How approvals work: https://corespeed.io/docs/approvals

### Do I have to switch agents?

No. CoreSpeed adds tools to the agent you already use: Claude Code, Codex, Cursor, or another MCP client. Each one signs in once.

### Can my agent access every account in our organization?

No. Access follows your CoreSpeed identity, each connection's visibility, and the app's own permissions. Personal connections stay private.

### Does this work without connecting an account?

No. Connect the app's account first; your CoreSpeed workspace shows what each app needs. The examples on this page use fictional data. All connectors: https://corespeed.io/docs/connectors
