# Connect Apps

Connect Claude to 1000+ apps using the [Composio CLI](https://docs.composio.dev/docs/cli). Actually send emails, create issues, post messages - not just generate text about it.

## Quick Start

### Step 1: Install the Composio CLI

```bash
curl -fsSL https://composio.dev/install | bash
```

### Step 2: Log In

```bash
composio login
composio whoami
```

Opens a browser for auth, then prompts you to pick a default org and project. Use `-y` to skip prompts in scripts.

### Step 3: Link the Apps You Need

```bash
composio link gmail
composio link slack
composio link github
```

Each command walks OAuth once; the connection then persists.

### Step 4: Try It

```bash
composio execute GMAIL_SEND_EMAIL -d '{
  "recipient_email": "YOUR_EMAIL@example.com",
  "subject": "Composio test",
  "body": "Hello from the CLI"
}'
```

If the email arrives, you're connected.

## What You Can Do

| Ask Claude to... | Claude runs |
|------------------|-------------|
| "Send email to sarah@acme.com about the launch" | `composio execute GMAIL_SEND_EMAIL -d '{...}'` |
| "Create GitHub issue: fix login bug" | `composio execute GITHUB_CREATE_ISSUE -d '{...}'` |
| "Post to Slack #general: deploy complete" | `composio execute SLACK_SEND_MESSAGE -d '{...}'` |
| "Add meeting notes to Notion" | `composio execute NOTION_CREATE_PAGE -d '{...}'` |

## Core Workflow

1. **Know the tool slug?** → `composio execute <SLUG> -d '{...}'`
2. **Don't know it?** → `composio search "what you want"`
3. **Need inputs?** → `composio execute <SLUG> --get-schema` or `--dry-run`
4. **Not connected?** → `composio link <toolkit>` and retry
5. **Multi-step?** → `composio run` for JS/TS workflows, `composio proxy` for raw API

## 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...**

## Handy Commands

```bash
# Discover tools
composio search "create a github issue"
composio tools list gmail
composio tools info GITHUB_CREATE_ISSUE

# Inspect / dry-run before executing
composio execute GITHUB_CREATE_ISSUE --get-schema
composio execute GITHUB_CREATE_ISSUE --dry-run -d '{"owner":"acme","repo":"app","title":"Bug"}'

# Execute in parallel
composio execute --parallel \
  GMAIL_FETCH_EMAILS -d '{"max_results": 2}' \
  GITHUB_GET_THE_AUTHENTICATED_USER -d '{}'

# Multi-step workflow
composio run '
  const issue = await execute("GITHUB_CREATE_ISSUE", {
    owner: "acme", repo: "app", title: "Bug", body: "..."
  });
  console.log(issue);
'

# Raw API call when no dedicated tool exists
composio proxy https://gmail.googleapis.com/gmail/v1/users/me/profile --toolkit gmail
```

## Configuration

**Environment variables:**
- `COMPOSIO_API_KEY` - auth credential for non-interactive use
- `COMPOSIO_BASE_URL` - custom API endpoint
- `COMPOSIO_SESSION_DIR` - override artifact storage
- `COMPOSIO_DISABLE_TELEMETRY=true` - opt out

**Global flags:** `--log-level <all|trace|debug|info|warning|error|fatal|none>`, `--help`.

## Troubleshooting

- **`Not logged in`** → run `composio login`
- **`Connection required for <toolkit>`** → run `composio link <toolkit>`
- **Unknown slug** → `composio search "<goal>"` or `composio tools list <toolkit>`
- **Bad inputs** → `composio execute <SLUG> --get-schema` then `--dry-run`
- **Action failed** → check permissions in the target app
