OpenClaw is the fastest growing agent harness out there, which can work 24/7 to automate almost any kind of tasks. However, its capabilities are limited to the tools it has access to. Composio allows your OpenClaw to access Mails so with authentication management handled for you. You can execute actions on Mails so via your favorite OpenClaw interface (Telegram, WhatsApp, TUI, etc), whichever you prefer.

Why use Composio?
Apart from a managed and hosted MCP server, you will get:
- Programmatic tool calling allows LLMs to write its code in a remote workbench to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
- Handling Large tool responses out of LLM context to minimize context rot.
- Dynamic just-in-time access to 20,000 tools across 850+ other Apps for cross-app workflows. It loads the tools you need, so LLMs aren't overwhelmed by tools you don't need.
How to install Mails so with OpenClaw
Using Composio API Key and Setup Prompt
- Go to dashboard.composio.dev/composio/~/connect/clients/openclaw
- Copy the setup prompt
- Run it in your OpenClaw chat interface.
- Authenticate Mails so from the dashboard
- Go back to your OpenClaw interface and start asking questions.
Using OpenClaw/Composio Plugin
1. Install OpenClaw Composio plugin
2. Copy the API Key from dashboard.composio.dev
3. Setup OpenClaw Config
openclaw config set plugins.entries.composio.config.consumerKey "ck_your_key_here"4. Restart OpenClaw
openclaw gateway restart5. Go to your chat interface and start asking questions.
6. When prompted, authenticate the app and you're all set.
How It Works
The plugin connects to Composio's MCP server at https://connect.composio.dev/mcp and registers all available tools directly into the OpenClaw agent. Tools are called by name — no extra search or execute steps needed.
If a tool returns an auth error, the agent will prompt you to connect that toolkit at dashboard.composio.dev.

What is the Mails so MCP server, and what's possible with it?
The Mails so MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Mails so account. It provides structured and secure access to advanced email validation services, so your agent can perform actions like verifying single emails, running bulk checks, and retrieving validation results on your behalf.
- Single email validation: Instantly check if an individual email address is valid and safe to use before sending important messages.
- Bulk email validation: Submit large lists of email addresses for automated deliverability and quality checks, keeping your contact databases clean.
- Batch results retrieval: Effortlessly fetch detailed validation outcomes for previously submitted bulk jobs, so you can review and act on the results.
- Email list hygiene automation: Use the agent to regularly scan and validate contact lists, reducing bounce rates and improving sender reputation.

FAQ
What are the differences in Tool Router MCP and Mails so MCP?
With a standalone Mails so MCP server, the agents and LLMs can only access a fixed set of Mails so tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Mails so and many other apps based on the task at hand, all through a single MCP endpoint.
Can I use Tool Router MCP with OpenClaw?
Yes, you can. OpenClaw 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 Mails so tools.
Can I manage the permissions and scopes for Mails so while using Tool Router?
Yes, absolutely. You can configure which Mails so 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 Mails so data and credentials are handled as safely as possible.
