## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `MX_TOOLBOX_LOOKUP_BIMI_RECORD` | Lookup BIMI Record | Retrieves BIMI (Brand Indicators for Message Identification) record and diagnostic information for a domain. BIMI allows organizations to display verified logos in email clients. This tool checks: - Whether a BIMI record exists at default._bimi.{domain} - DMARC policy requirements (quarantine or reject needed for BIMI) - DNS resolution details and nameserver information - Related diagnostic checks and recommendations Returns comprehensive lookup data including passed/failed checks, DMARC records, DNS transcript, and related lookups. Use when verifying email branding configuration or troubleshooting BIMI implementation. |
| `MX_TOOLBOX_LOOKUP_BLACKLIST` | Lookup Blacklist | Tool to perform a blacklist check on a domain or IP. Use when you need to verify whether a domain or IP is listed in common blacklists. |
| `MX_TOOLBOX_LOOKUP_DKIM` | Lookup DKIM Record | Tool to retrieve DKIM (DomainKeys Identified Mail) records for a domain. DKIM is an email authentication method that helps prevent email spoofing by allowing the receiver to verify that an email was actually sent and authorized by the owner of that domain. Use this tool to verify DKIM configuration and troubleshoot email authentication issues. |
| `MX_TOOLBOX_LOOKUP_DMARC` | Lookup DMARC Record | Retrieves DMARC (Domain-based Message Authentication, Reporting & Conformance) records for a domain and performs validation checks. Returns detailed information about the DMARC record including policy settings (reject/quarantine/none), reporting addresses, alignment modes, and diagnostic check results. Useful for verifying email authentication configuration and troubleshooting email delivery issues. |
| `MX_TOOLBOX_LOOKUP_DNS` | Lookup DNS Records | Performs comprehensive DNS health check and retrieves name server records for a domain. Returns detailed diagnostics including: - Name server (NS) records with IP addresses, TTL, and status - DNS configuration health checks (warnings, errors, passed tests) - Query transcripts showing DNS resolution path - Related lookup suggestions (A, MX, SPF records) Use this to diagnose DNS issues, verify name server configurations, or check DNS propagation status. |
| `MX_TOOLBOX_LOOKUP_HTTP` | HTTP Lookup | Tool to perform an HTTP test on a domain. Use when you need to assess HTTP connectivity and status for a given domain. |
| `MX_TOOLBOX_LOOKUP_MTA_STS_RECORD` | Lookup MTA-STS Record | Tool to lookup MTA-STS record for a domain. Use when validating mail transport security policy. |
| `MX_TOOLBOX_LOOKUP_MX` | Lookup MX Records | Retrieves MX (Mail Exchange) records for a domain. Returns the mail servers responsible for receiving email for the domain, including their priority, hostname, IP address, and TTL. Use this to discover and verify email infrastructure for any domain. |
| `MX_TOOLBOX_LOOKUP_PING` | Ping Lookup | Performs a ping test to check network connectivity and measure round-trip time to a domain or IP address. Returns detailed ping statistics including response time, TTL (Time-To-Live), packet size, and ASN (Autonomous System Number) information. Useful for diagnosing network connectivity issues, measuring latency, and verifying host availability. |
| `MX_TOOLBOX_LOOKUP_SMTP` | SMTP Lookup | Tool to perform an SMTP connectivity test on a domain. Returns diagnostic results including connection status, DNS checks, TLS support, and other email deliverability indicators. Use when verifying SMTP server configuration or troubleshooting email delivery issues for a domain. |
| `MX_TOOLBOX_LOOKUP_SPF` | Lookup SPF Record | Tool to retrieve SPF records for a specified domain. Use when confirming email sender authorization policies. |
| `MX_TOOLBOX_MONITOR_STATUS` | Monitor Status | Retrieves the current status of all monitors configured in the MX Toolbox account. This action returns a list of all monitors with their health status, last check time, reputation scores, and any failing checks or warnings. Use this when you need to: - Check the overall health of all configured monitors - Get a comprehensive view of monitoring status across all services - Identify which monitors are failing or have warnings - Review when monitors were last checked No parameters are required - this action retrieves all monitors for the authenticated account. Returns an empty list if no monitors are configured. |
| `MX_TOOLBOX_USAGE_CHECK` | Check Usage | Retrieve API usage statistics for DNS and network lookups. Returns current request counts, maximum allowed requests, and any overage errors for both DNS lookups and network operations (HTTP, SMTP, Ping). |

```python
pip install composio_openai
```

```typescript

```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')
```

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 Mx toolbox Tools via Tool Router with Your Agent

Get tools from Tool Router session and execute Mx toolbox actions with your Agent
```python
tools = session.tools
response = openai.responses.create(
  model='gpt-4.1',
  tools=tools,
  input=[{
    'role': 'user',
    'content': 'Check if example.com is blacklisted on major DNSBLs'
  }]
)
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: 'Check if example.com is blacklisted on major DNSBLs'
  }],
});
const result = await composio.provider.handleToolCalls(
