# 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

Overview

This skill connects Claude to 1000+ external apps so the assistant can actually perform actions like sending emails, creating issues, and posting messages. It installs a tool router plugin and guides you through a one-time OAuth setup to authorize services. After setup, Claude can execute real-world tasks across email, chat, dev, docs, and data platforms.

How this skill works

Install the Composio Tool Router plugin and run its setup command to provide a free API key and configure integrations. When you ask Claude to take an action, the router selects the appropriate connector, prompts for OAuth if needed, and executes the action, returning the result. Most authorizations are one-time; subsequent requests use stored tokens to complete tasks automatically.

When to use it

  • Send actual emails or messages from Claude instead of draft text.
  • Create issues, tickets, or pull requests across GitHub/GitLab/Jira/Linear.
  • Add or update content in Notion, Google Docs, Sheets, or Airtable.
  • Post to Slack, Teams, Discord, or Telegram channels.
  • Run simple database updates or append rows to spreadsheets and data stores.

Best practices

  • Install and run the setup flow immediately to authorize commonly used apps via OAuth.
  • Start with simple, low-risk actions (test email, a Slack test message) to confirm permissions.
  • Specify recipients, channels, titles, and bodies clearly so Claude can map fields to the target app.
  • Verify and limit permissions for service accounts and OAuth tokens to reduce blast radius.
  • Check app-side permissions and role access if an action fails; the tool executes with your granted rights.

Example use cases

  • "Send email to [email protected] with subject: Launch update" — actually sends the message via Gmail or Outlook.
  • "Create GitHub issue: fix login error" — creates a properly formatted issue in a repo.
  • "Post to Slack #dev: deployment succeeded" — posts the message in the specified channel.
  • "Add meeting notes to Notion under Project X" — appends notes to a Notion page or database.
  • "Append this sales row to our Google Sheet" — writes structured data to Sheets or Airtable.

FAQ

Do I need to authorize each app separately?

Typically you authorize each app once via OAuth during the setup flow or when first used; subsequent calls reuse the stored tokens.

What if an action fails with permission errors?

Confirm the OAuth account has the required role in the target app, then reauthorize if needed. Also ensure the plugin is installed and connected.
