/slack-channel:configure

Overview

Configure the Slack channel MCP plugin by providing your Slack bot token and app-level token. Writes credentials to a secure

.env

file with owner-only permissions.

Prerequisites

A Slack app created at api.slack.com/apps with Socket Mode enabled
A Bot User OAuth Token (
```
xoxb-...
```
) from OAuth & Permissions
An App-Level Token (
```
xapp-...
```
) from Socket Mode settings
Write access to
```
~/.claude/channels/slack/
```

Usage

/slack-channel:configure <xoxb-bot-token> <xapp-app-token>

Instructions

Parse the two arguments from
```
$ARGUMENTS
```
:
- First token must start with
```
xoxb-
```
  (Bot User OAuth Token)
- Second token must start with
```
xapp-
```
  (App-Level Token)

If either token is missing or has the wrong prefix, show this error and stop:

Error: Two tokens required.
  - Bot token (starts with xoxb-) from OAuth & Permissions
  - App token (starts with xapp-) from Socket Mode settings

Usage: /slack-channel:configure xoxb-... xapp-...

Create the state directory if it doesn't exist:

~/.claude/channels/slack/

Write the

.env

file at

~/.claude/channels/slack/.env

SLACK_BOT_TOKEN=<bot-token>
SLACK_APP_TOKEN=<app-token>

Set file permissions to owner-only:

chmod 600 ~/.claude/channels/slack/.env

Confirm success:

Slack channel configured.

Start Claude with the Slack channel:
  claude --channels plugin:slack-channel@claude-code-plugins

Or for development:
  claude --dangerously-load-development-channels server:slack

Security

Never echo the tokens back in the confirmation message
Never log tokens to stdout or any file other than
```
.env
```
Always set 0o600 permissions on the
```
.env
```
file

Output

On success, displays:

Slack channel configured.

Start Claude with the Slack channel:
  claude --channels plugin:slack-channel@claude-code-plugins

On validation failure, displays the error with correct usage syntax.

Error Handling

Error	Cause	Resolution

Invalid app token prefix	Second token does not start with `xapp-`	Explain where to find the App-Level Token in Socket Mode settings
