## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `BEEHIIV_CREATE_DRAFT_POST` | Create Draft Post | Create an unscheduled draft post from HTML content. This tool never confirms, publishes, schedules, or sends the post. Beehiiv creates posts asynchronously; the returned ID is stable while background creation finishes. |
| `BEEHIIV_CREATE_SEGMENT` | Create Segment | Create an audience segment from explicit subscription IDs, explicit emails, or custom-field rules; returns the segment and its initial calculation status. |
| `BEEHIIV_CREATE_SUBSCRIPTION` | Create Subscription | Create a new publication subscription without reactivating an unsubscribed address or sending a welcome email; supports attribution, initial custom fields, and newsletter-list assignment. |
| `BEEHIIV_LIST_CUSTOM_FIELDS` | List Custom Fields | List the custom-field definitions available for subscriber metadata and dynamic audience segments in a publication, returning one page controlled by page and limit with pagination metadata for retrieving additional fields. |
| `BEEHIIV_LIST_POSTS` | List Posts | Search a publication's posts by status, audience, channel, slug, tags, or author and optionally include content, recipients, or statistics. |
| `BEEHIIV_LIST_PUBLICATIONS` | List Publications | List publications accessible to the API key, optionally including publication statistics; use the returned publication IDs with publication-scoped tools. |
| `BEEHIIV_LIST_SEGMENT_MEMBERS` | List Segment Members | List full subscriber records currently included in an audience segment, optionally including stats, custom fields, referrals, tags, or premium tiers. The response contains subscriber PII. |
| `BEEHIIV_LIST_SEGMENTS` | List Segments | List audience segments in a publication, filtered by segment type or calculation status, with optional latest statistics. |
| `BEEHIIV_LIST_SUBSCRIPTIONS` | List Subscriptions | Search a publication's subscriptions by exact email or filter by status and tier, returning one cursor-controlled page of subscriber records. |
| `BEEHIIV_UPDATE_DRAFT_POST` | Update Draft Post | Update content or presentation settings on an existing draft after verifying it is still a draft; refuses confirmed, archived, or sent posts and cannot publish or schedule. |
| `BEEHIIV_UPDATE_SUBSCRIPTION_CUSTOM_FIELDS` | Update Subscription Custom Fields | Set or remove custom-field values on one subscription without changing its email, tier, billing link, or subscribed status. |

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 Beehiiv Tools via Tool Router with Your Agent

Get tools from Tool Router session and execute Beehiiv actions with your Agent
```python
tools = session.tools
response = openai.responses.create(
  model='gpt-4.1',
  tools=tools,
  input=[{
    'role': 'user',
    'content': 'Send newsletter to beta-subscribers segment'
  }]
)
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: 'Send newsletter to beta-subscribers segment'
  }],
});
const result = await composio.provider.handleToolCalls(
  'your-user-id',
  response.output
);
console.log(result);
```

```python
pip install composio claude-agent-sdk
```

```typescript
npm install @composio/core ai @ai-sdk/openai @ai-sdk/mcp
```

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

Import and initialize the Composio client, then create a Tool Router session for Beehiiv
```python
from composio import Composio
from claude_agent_sdk import ClaudeSDKClient, ClaudeAgentOptions

composio = Composio(api_key='your-composio-api-key')
session = composio.create(user_id='your-user-id')
url = session.mcp.url
```

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

const composio = new Composio({ apiKey: 'your-api-key' });
const session = await composio.create('your-user-id');
console.log(`Tool Router session created: ${session.mcp.url}`);
```

#### Path 2, Step 3: Connect to AI Agent

Use the MCP server with your AI agent (Anthropic Claude or Mastra)
```python
import asyncio

options = ClaudeAgentOptions(
    permission_mode='bypassPermissions',
    mcp_servers={
        'tool_router': {
            'type': 'http',
            'url': url,
            'headers': {
                'x-api-key': 'your-composio-api-key'
            }
        }
    },
    system_prompt='You are a helpful assistant with access to Beehiiv tools.',
    max_turns=10
)

async def main():
    async with ClaudeSDKClient(options=options) as client:
        await client.query('Send newsletter to beta-subscribers segment')
        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: 'Send newsletter to beta-subscribers segment'
  }],
  maxSteps: 5,
});

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