## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `MAILDROPPA_ARCHIVE_TAG` | Archive Tag | Archive one customer-managed tag. Archiving prevents new assignments but preserves existing subscriber assignments and can be reversed by restoring the tag. Use the tag-usage tool first to inspect archive blockers. |
| `MAILDROPPA_COUNT_SEGMENT_SUBSCRIBERS` | Count Segment Subscribers | Return the current number of subscribers matching one stored segment. |
| `MAILDROPPA_CREATE_SEGMENT` | Create Segment | Create a subscriber segment from field, tag, or nested-segment conditions. |
| `MAILDROPPA_CREATE_SUBSCRIBER` | Create Subscriber | Create a subscriber without sending an opt-in message, with optional typed field values and tag assignments. |
| `MAILDROPPA_CREATE_SUBSCRIBERS` | Create Subscribers | Sequentially create 1-25 subscribers without sending opt-in messages. The batch is non-atomic, returns an outcome for every item, and stops after a systemic or ambiguous failure. |
| `MAILDROPPA_CREATE_TAG` | Create Tag | Create a customer-managed tag that can be assigned to subscribers. |
| `MAILDROPPA_DELETE_SEGMENT` | Delete Segment | Permanently delete exactly one stored subscriber segment identified by an explicit segment ID. This action cannot select segments by filter or bulk criteria. |
| `MAILDROPPA_DELETE_SUBSCRIBER` | Delete Subscriber | Permanently delete exactly one subscriber identified by an explicit subscriber ID. This action cannot select subscribers by email, filter, or bulk criteria. |
| `MAILDROPPA_GET_FORM_EMBEDDING` | Get Form Embedding | Return an active Maildroppa form's ordered input-field definition for rendering in a trusted website integration. |
| `MAILDROPPA_GET_SEGMENT` | Get Segment | Return one stored subscriber segment and its complete filter expression by ID. |
| `MAILDROPPA_GET_SUBSCRIBER` | Get Subscriber | Return one Maildroppa subscriber by ID, including display field values, tag IDs, status, registration date, and GDPR agreement. |
| `MAILDROPPA_GET_TAG_USAGE` | Get Tag Usage | Return subscriber assignments and archive or permanent-delete blockers for one Maildroppa tag. |
| `MAILDROPPA_LIST_FORMS` | List Forms | Return signup form overviews with IDs, type, status, publication state, and public routing details. |
| `MAILDROPPA_LIST_RSS_NEWSLETTERS` | List RSS Newsletters | Return the account's RSS newsletter configurations without activating, checking, or sending them. |
| `MAILDROPPA_LIST_RSS_SENDER_PROFILES` | List RSS Sender Profiles | Return sender profiles available to RSS newsletters, including verification and delivery readiness. |
| `MAILDROPPA_LIST_SEGMENTS` | List Segments | Return the account's stored subscriber segments and filter expressions. |
| `MAILDROPPA_LIST_SUBSCRIBER_ACTIVITY` | List Subscriber Activity | Return one page of a subscriber's activity timeline with delivery eligibility and summary counts. |
| `MAILDROPPA_LIST_SUBSCRIBER_FIELDS` | List Subscriber Fields | Return built-in and custom subscriber field definitions, optionally including archived custom fields. |
| `MAILDROPPA_LIST_SUBSCRIBERS` | List Subscribers | Return one page of subscribers, optionally filtered by free text, status, or structured segment conditions. Pass next_cursor back as cursor to continue. |
| `MAILDROPPA_LIST_TAGS` | List Tags | Return account tags, optionally including archived tags. |
| `MAILDROPPA_RESTORE_TAG` | Restore Tag | Restore an archived customer-managed Maildroppa tag so it can be assigned to subscribers again. |
| `MAILDROPPA_UPDATE_SEGMENT` | Update Segment | Replace a segment's name and complete filter expression. This is a full replacement, so supply every condition group that should remain. |
| `MAILDROPPA_UPDATE_TAG` | Update Tag | Rename an existing customer-managed tag. |

Install the Composio SDK
```python
pip install composio_openai
```

```typescript
npm install @composio/openai
```

#### Path 1, Step 2: Initialize Composio and Create Tool Router Session

Import and initialize Composio client, then create a Tool Router session
```python
from openai import OpenAI
from composio import Composio
from composio_openai import OpenAIResponsesProvider

composio = Composio(provider=OpenAIResponsesProvider())
openai = OpenAI()
session = composio.create(user_id='your-user-id')
```

```typescript
import OpenAI from 'openai';
import { Composio } from '@composio/core';
import { OpenAIResponsesProvider } from '@composio/openai';

const composio = new Composio({
  provider: new OpenAIResponsesProvider(),
});
const openai = new OpenAI({});
const session = await composio.create('your-user-id');
```

#### Path 1, Step 3: Execute Maildroppa Tools via Tool Router with Your Agent

Get tools from Tool Router session and execute Maildroppa actions with your Agent

  tools=tools,
  input=[{
    'role': 'user',
    'content': 'YOUR_SPECIFIC_PROMPT_HERE'
  }]
)
result = composio.provider.handle_tool_calls(
  response=response,
  user_id='your-user-id'
)
print(result)
```

```typescript
const tools = session.tools;
const response = await openai.responses.create({
  model: 'gpt-4.1',
  tools: tools,
  input: [{
    role: 'user',
    content: 'YOUR_SPECIFIC_PROMPT_HERE'
  }],
});
const result = await composio.provider.handleToolCalls(

        'tool_router': {
            'type': 'http',
            'url': url,
            'headers': {
                'x-api-key': 'your-composio-api-key'
            }
        }
    },
    system_prompt='You are a helpful assistant with access to Maildroppa tools.',
    max_turns=10
)

async def main():
    async with ClaudeSDKClient(options=options) as client:
        await client.query('YOUR_SPECIFIC_PROMPT_HERE')
        async for message in client.receive_response():
            if hasattr(message, 'content'):
                for block in message.content:
                    if hasattr(block, 'text'):
                        print(block.text)

asyncio.run(main())
```

```typescript
import { openai } from '@ai-sdk/openai';
import { experimental_createMCPClient as createMCPClient } from '@ai-sdk/mcp';
import { generateText } from 'ai';

const client = await createMCPClient({
  transport: {
    type: 'http',
    url: session.mcp.url,
    headers: {
      'x-api-key': 'your-composio-api-key',
    },
  },
});

const tools = await client.tools();
const { text } = await generateText({
  model: openai('gpt-4o'),
  tools,
  messages: [{
    role: 'user',
    content: 'YOUR_SPECIFIC_PROMPT_HERE'
  }],
  maxSteps: 5,
});

console.log(`Agent: ${text}`);
