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 Emailable account to Cowork via Composio Connect, enabling it to check if this email address is valid, verify a list of emails before newsletter send, get your Emailable account credit balance, and more such actions on your behalf without compromising your account security. ## Also integrate Emailable with - [OpenAI Agents SDK](https://composio.dev/toolkits/emailable/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/emailable/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/emailable/framework/claude-code) - [Codex](https://composio.dev/toolkits/emailable/framework/codex) - [OpenClaw](https://composio.dev/toolkits/emailable/framework/openclaw) - [Hermes](https://composio.dev/toolkits/emailable/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/emailable/framework/cli) - [Google ADK](https://composio.dev/toolkits/emailable/framework/google-adk) - [LangChain](https://composio.dev/toolkits/emailable/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/emailable/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/emailable/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/emailable/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/emailable/framework/crew-ai) ## Connect Emailable to Claude Cowork ### Connecting Emailable to Claude Cowork 1. Open Customize In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top. 2. Add the Composio MCP server Click Add custom connector and paste in the Composio MCP server URL: ```bash https://connect.composio.dev/mcp ``` ## 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 Emailable through MCP without you sharing account credentials directly with the agent. ## What is the Emailable MCP server, and what's possible with it? The Emailable MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Emailable account. It provides structured and secure access to your email verification services, so your agent can perform actions like real-time email validation, bulk batch checks, account monitoring, and verification status tracking on your behalf. - Instant email address verification: Ask your agent to check if a single email address is valid, risky, or deliverable before you send that important message. - Bulk batch email validation: Have the agent verify thousands of email addresses at once for newsletters, campaigns, or CRM imports, ensuring high deliverability rates. - Batch job status monitoring: Let your agent track the progress and results of ongoing or completed batch verification jobs for timely follow-up actions. - Account status and credit checks: Retrieve your Emailable account details, including owner info and available credits, to make sure you never run out of verification capacity. - Seamless OAuth onboarding: Initiate the OAuth flow to securely grant your agent access to Emailable whenever needed, all without manual credential handling. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `EMAILABLE_GET_ACCOUNT_INFO` | Get Account Info | Tool to retrieve account information including owner email and available credits. Use when you need to confirm account status before sending email verifications. | | `EMAILABLE_GET_BATCH_STATUS` | Get Batch Status | Tool to get the status and results of a batch verification job. Use after submitting a batch to check its progress. | | `EMAILABLE_O_AUTH_AUTHORIZE` | Build OAuth Authorization URL | Build an OAuth 2.0 authorization URL for the Emailable authorization code flow. Returns a URL to redirect users to for authorization. Upon successful authorization, users are redirected to your redirect_uri with an authorization code (valid for 10 minutes) that can be exchanged for access tokens. | | `EMAILABLE_VERIFY_BATCH_EMAILS` | Verify Batch Emails | Submit a batch of email addresses for asynchronous verification. Returns a batch ID immediately. Use this for bulk email validation (2 to 50,000 emails). For single emails, use EMAILABLE_VERIFY_EMAIL instead. The batch is processed asynchronously - use EMAILABLE_GET_BATCH_STATUS with the returned batch ID to check progress and retrieve verification results. | | `EMAILABLE_VERIFY_EMAIL` | Verify Email | Tool to verify a single email address and return detailed results. Use when you need to check email deliverability and risk. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Emailable MCP server connects Claude Cowork to your Emailable account through Composio. Once connected, Cowork can use the available Emailable tools and triggers to complete tasks on your behalf. ## Complete Code None listed. ## How to build Emailable MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/emailable/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/emailable/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/emailable/framework/claude-code) - [Codex](https://composio.dev/toolkits/emailable/framework/codex) - [OpenClaw](https://composio.dev/toolkits/emailable/framework/openclaw) - [Hermes](https://composio.dev/toolkits/emailable/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/emailable/framework/cli) - [Google ADK](https://composio.dev/toolkits/emailable/framework/google-adk) - [LangChain](https://composio.dev/toolkits/emailable/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/emailable/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/emailable/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/emailable/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/emailable/framework/crew-ai) ## Related Toolkits - [Supabase](https://composio.dev/toolkits/supabase) - Supabase is an open-source backend platform offering scalable Postgres databases, authentication, storage, and real-time APIs.

With a standalone Emailable MCP server, the agents and LLMs can only access a fixed set of Emailable tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Emailable 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 Emailable tools. ### Can I manage the permissions and scopes for Emailable while using Tool Router? Yes, absolutely. You can configure which Emailable 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 Emailable data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) ยท [Composio docs](https://docs.composio.dev/llms.txt)
