# Connect Apps
Connect Claude to 1000+ apps. Actually send emails, create issues, post messages - not just generate text about it.
## Quick Start
### Step 1: Install the Plugin
```
/plugin install composio-toolrouter
```
### Step 2: Run Setup
```
/composio-toolrouter:setup
```
This will:
- Ask for your free API key (get one at [platform.composio.dev](https://platform.composio.dev/?utm_source=Github&utm_content=AwesomeSkills))
- Configure Claude's connection to 1000+ apps
- Take about 60 seconds
### Step 3: Try It!
After setup, restart Claude Code and try:
```
Send me a test email at [email protected]
```
If it works, you're connected!
## What You Can Do
| Ask Claude to... | What happens |
|------------------|--------------|
| "Send email to [email protected] about the launch" | Actually sends the email |
| "Create GitHub issue: fix login bug" | Creates the issue |
| "Post to Slack #general: deploy complete" | Posts the message |
| "Add meeting notes to Notion" | Adds to Notion |
## Supported Apps
**Email:** Gmail, Outlook, SendGrid
**Chat:** Slack, Discord, Teams, Telegram
**Dev:** GitHub, GitLab, Jira, Linear
**Docs:** Notion, Google Docs, Confluence
**Data:** Sheets, Airtable, PostgreSQL
**And 1000+ more...**
## How It Works
1. You ask Claude to do something
2. Composio Tool Router finds the right tool
3. First time? You'll authorize via OAuth (one-time)
4. Action executes and returns result
## Troubleshooting
- **"Plugin not found"** → Make sure you ran `/plugin install composio-toolrouter`
- **"Need to authorize"** → Click the OAuth link Claude provides, then say "done"
- **Action failed** → Check you have permissions in the target app
