## Description

Securely connect your AI agents and chatbots (Claude, ChatGPT, Cursor, etc) with Bouncify MCP or direct API to verify email addresses, validate bulk lists, check deliverability, and report remaining credits through natural language.

## Summary

Bouncify is an email verification service for single addresses and bulk lists.
Use it to reduce bounces, protect sender reputation, and track verification credits.

## Categories

- advertising & marketing

## Toolkit Details

- Tools: 7

## Images

## Authentication

- **Api Key**
  - Type: `api_key`
  - Description: Api Key authentication for Bouncify.
  - Setup:
    - Configure Api Key credentials for Bouncify.
    - Use the credentials when creating an auth config in Composio.

## Suggested Prompts

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `BOUNCIFY_CREATE_BULK_LIST` | Create Bulk List | Submit at least two email records for asynchronous bulk-job preparation without starting verification or consuming credits. Poll Get Bulk Job Status until the job is ready before starting verification. |
| `BOUNCIFY_DOWNLOAD_BULK_RESULTS` | Download Bulk Results | Download selected result classes from a completed bulk-verification job as a CSV file. |
| `BOUNCIFY_GET_BULK_JOB_STATUS` | Get Bulk Job Status | Return a bulk job's preparation or verification state, progress, analysis, and result counts. Treat status as authoritative: a failed job can still have success=true. |
| `BOUNCIFY_GET_CREDIT_BALANCE` | Get Credit Balance | Return the connected Bouncify account's remaining verification credits without consuming a credit. |
| `BOUNCIFY_REQUEST_BULK_LIST_DELETION` | Request Bulk List Deletion | Permanently request deletion of a bulk list and its results. This operation is irreversible. Bouncify acknowledges an asynchronous or delayed deletion, so success means the request was accepted, not that the job has already disappeared. |
| `BOUNCIFY_START_BULK_VERIFICATION` | Start Bulk Verification (Irreversible, Consumes Credits) | Irreversibly start verification for a prepared bulk list. This consumes one verification credit per email and, after a successful start, cannot be paused, stopped, cancelled, or restarted. Check that the job is ready and sufficient credits remain before invoking. The response only acknowledges the start; use Get Bulk Job Status to monitor progress. |
| `BOUNCIFY_VERIFY_EMAIL` | Verify Email (Consumes Credit) | Verify one email address in real time. Every successful API call consumes one verification credit, including an address that Bouncify classifies as invalid syntax. |

## Installation and MCP Setup

### Path 1: SDK Installation

#### Path 1, Step 1: Install Composio

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 Bouncify Tools via Tool Router with Your Agent

Get tools from Tool Router session and execute Bouncify actions with your Agent
```python
tools = session.tools
response = openai.responses.create(
  model='gpt-4.1',
  tools=tools,
  input=[{
    'role': 'user',
    'content': 'Verify jane@example.com with Bouncify and tell me if it is deliverable.'
  }]
)
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: 'Verify jane@example.com with Bouncify and tell me if it is deliverable.'
  }],
});
const result = await composio.provider.handleToolCalls(
  'your-user-id',
  response.output
);
console.log(result);
```

### Path 2: MCP Server Setup

#### Path 2, Step 1: Install Composio

Install the Composio SDK for Python or TypeScript
```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 Bouncify
```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 Bouncify tools.',
    max_turns=10
)

async def main():
    async with ClaudeSDKClient(options=options) as client:
        await client.query('Check my remaining Bouncify verification credits.')
        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: 'Check my remaining Bouncify verification credits.'
  }],
  maxSteps: 5,
});

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