# Make your MCP token

Your MCP token is your email address and agent password joined with a colon, then encoded in base64, with no spaces. On Mac or Linux run the printf command below in Terminal; on Windows run the PowerShell command. Your assistant sends it as `Authorization: Bearer <token>`. Base64 is not encryption, so keep the token as secret as a password.

## How to make your MCP token

1. Have your email address and agent password ready.
2. Run the command for your computer, replacing the example address and AGENT_PASSWORD with yours.
3. Copy the line it prints. That is your token.
4. Paste the token into your AI client's settings where the setup guide says `<TOKEN>`.

## When to use it

> Meera has created her agent password. She opens PowerShell, runs the command with her address and agent password, and copies the line it prints into her Cursor settings.

## Commands

**Mac or Linux (Terminal):**

```
printf '%s' 'you@xgenplus.com:AGENT_PASSWORD' | base64 | tr -d '\n'
```

The `tr` part removes the line break Linux adds to long tokens.

**Windows (PowerShell):**

```
[Convert]::ToBase64String([Text.Encoding]::UTF8.GetBytes('you@xgenplus.com:AGENT_PASSWORD'))
```

## Good to know

- **Base64 is not encryption.** Anyone with the token can use your agent password. Keep it as secret as a password.
- If you change your agent password, make a new token.
- Use the whole address, such as you@yourcompany.com, not just your name.

## Common questions

**Is the token safe to share?**

No. It is your agent password in another form. Never paste it into a chat with the AI, into shared files or into a code repository.

**My client still asks me to sign in. What is wrong?**

The token is missing or wrong. Make it again with no spaces or line breaks, and check the header reads Authorization, Bearer, a space, then the token.
