## Introduction

Cowork is Anthropic's AI agent for knowledge work. Think of it as Claude Code for everything else. It works autonomously with your computer, local files, and applications to accomplish complex tasks.
This guide walks you through the easiest and most secure way to connect your Malwarebytes account to Cowork via Composio Connect, enabling it to check suspicious login link safety, verify sender domain before replying, analyze phone number for threats, and more such actions on your behalf without compromising your account security.

## What is Claude Cowork?

Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools.
With Composio Connect, Cowork can securely access apps like Malwarebytes through MCP without you sharing account credentials directly with the agent.

## What is the Malwarebytes MCP server, and what's possible with it?

The Malwarebytes MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Malwarebytes account. It provides structured and secure access so your agent can perform Malwarebytes operations on your behalf.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `MALWAREBYTES_MCP_REPUTATION_CHECK_EMAIL` | Reputation-check email | Use this when you need to check if an email address is associated with phishing, scams, or malicious activity. Checks the email domain against threat intelligence database. Returns one of: - malicious: Confirmed phishing or malicious email domain - suspicious: Potentially dangerous email domain - safe: Verified legitimate email domain - unknown: No threat intelligence available Cross-tool workflow: - If the email contains URLs, consider scanning them with reputation-check_link. - If the email contains phone numbers, consider scanning them with reputation-check_phone. - For unknown or suspicious verdicts, consider using reputation-whois to check domain registration details (age, registrar, abuse contact). Do not use this for email validation, mailbox verification, or general email lookup services. |
| `MALWAREBYTES_MCP_REPUTATION_CHECK_LINK` | Reputation-check link | Use this when you need to check if a link or URL is safe, suspicious, or malicious. Provides reputation verdict based on threat intelligence database. Returns one of: - malicious: Confirmed harmful link - suspicious: Potentially dangerous link - safe: Verified safe link - unknown: No threat intelligence available Cross-tool workflow: - For unknown or suspicious verdicts, consider using reputation-whois to check domain registration details (age, registrar, abuse contact). - If the URL redirects to a different domain, consider scanning the destination URL separately. - If the URL came from an email or text message, consider checking the sender with reputation-check_email or reputation-check_phone. Do not use this for general web searches, content fetching, or webpage analysis. |
| `MALWAREBYTES_MCP_REPUTATION_CHECK_PHONE` | Reputation-check phone | Use this when you need to check if a phone number is associated with scams or suspicious activity. Provides reputation verdict and additional phone information. Returns one of: - malicious: Confirmed scam or spam phone number - suspicious: Potentially dangerous number - safe: Verified legitimate number - unknown: No threat intelligence available Also provides optional details like carrier, location, and phone type when available. Cross-tool workflow: - If the caller provided links, consider scanning them with reputation-check_link. - If the caller provided email addresses, consider scanning them with reputation-check_email. Do not use this for phone number lookups, caller ID services, or general phone directory searches. |
| `MALWAREBYTES_MCP_REPUTATION_REPORT` | Reputation-report | Use this when a user wants to report a suspicious link, email address, or phone number. Submits the indicator to the threat intelligence system for analysis. Only use when explicitly requested by the user. Do not use this to automatically report every checked item. |
| `MALWAREBYTES_MCP_REPUTATION_SCAN_ALL` | Reputation-scan all | Use this when you need to check multiple links, emails, or phone numbers at once. Scans all indicators concurrently and returns a unified result. Each indicator needs: - type: 'url', 'email', or 'phone' - value: the URL, email address, or phone number (E.164 format for phones) Returns a summary with counts per verdict and individual results for each indicator. Prefer this over individual scan tools when 3 or more indicators are present. Maximum 10 indicators per request. Cross-tool workflow: - For unknown URL or email verdicts, consider using reputation-whois on the associated domains for additional registration context and abuse contact information. |
| `MALWAREBYTES_MCP_REPUTATION_WHOIS` | Reputation-whois | Use this when you need to look up domain registration information to verify legitimacy or identify suspicious patterns. Provides WHOIS/RDAP data including registrar, registration dates, name servers, and abuse contacts. Particularly useful for identifying newly registered domains (common in phishing and scams). Returns the registrar's abuse contact email when available, which can be used for filing complaints about fraudulent domains. Cross-tool workflow: - Consider using reputation-check_link to check the domain's threat reputation alongside WHOIS registration data. Do not use this for general domain availability checks or bulk domain searches. |

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Malwarebytes MCP?

With a standalone Malwarebytes MCP server, the agents and LLMs can only access a fixed set of Malwarebytes tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Malwarebytes and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Claude Cowork?

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Malwarebytes tools.

### Can I manage the permissions and scopes for Malwarebytes while using Tool Router?

Yes, absolutely. You can configure which Malwarebytes scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Malwarebytes data and credentials are handled as safely as possible.
