How to integrate Listclean MCP with Hermes

Hermes is a 24/7 autonomous agent that lives on your computer or server — it remembers what it learns and evolves as your usage grows. This guide explains the easiest and most robust way to connect your Listclean account to Hermes. You can do this through either Composio Connect CLI or Composio Connect MCP. For personal use we recommend the CLI, but you won't go wrong with MCP either.

What is Composio Connect?

Composio Connect is a consumer offering that lets anyone plug 1,000+ applications directly into their agent harness — including Hermes. It can:

  • Search and load tools from relevant toolkits on-demand, reducing context usage.
  • Chain multiple tools to accomplish complex workflows via a remote workbench, without excessive back-and-forth with the LLM.
  • Manage app authentication end-to-end with zero manual overhead.

Integrating Listclean with Hermes

Using Composio Connect CLI

1. Install the Composio CLI

Run the install script directly, or paste https://composio.dev/hermes into your Hermes chat box to have it installed for you.

bash
curl -fsSL https://composio.dev/install | bash
Hermes authenticating with Composio

2. Authenticate

Once the CLI is installed, ask Hermes to authenticate with Composio.

3. Connect to Listclean

Ask your agent to connect to Listclean, or simply request any Listclean-related task. Hermes will prompt you to authenticate and authorize access.

4. Done. You're all set with a new Listclean connection.


Using Composio Connect MCP

1. Get your MCP URL and API Key

Go to dashboard.composio.dev and copy your Connect MCP URL and API key.

Copy MCP URL and API key from Composio dashboard

2. Open the Hermes config file

bash
nano ~/.hermes/config.yaml

3. Add the Composio Connect MCP server

bash
mcp_servers:
  composio:
    url: "https://connect.composio.dev/mcp"
    headers:
      x-consumer-api-key: "YOUR_COMPOSIO_API_KEY"
    connect_timeout: 60
    timeout: 180

Save with Ctrl + O, Enter, then exit with Ctrl + X.

4. Restart your Hermes agent

Once restarted, ask your agent to connect to Listclean or request any Listclean-related task. It will prompt you to authenticate and authorize access.

5. Done!

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

The Listclean MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Listclean account. It provides structured and secure access to your email verification tools, so your agent can perform actions like verifying emails, managing bulk verification lists, checking credits, and retrieving account info on your behalf.

  • Single email verification: Instantly check if an email address is valid, deliverable, or disposable—perfect for real-time signups or contact forms.
  • Bulk email list processing: Have your agent generate and upload CSV files of email addresses for large-scale verification and list cleaning.
  • Account credit monitoring: Easily monitor your remaining verification credits so your automations never hit a surprise limit.
  • Profile data retrieval: Let your agent fetch and review your Listclean account profile details for audits or reporting purposes.

Way Forward

With Listclean connected, Hermes can now act on your behalf whenever it detects a relevant task or you ask it to.

From here, you can extend Hermes further:

  • Connect more apps: Calendar, Slack, Notion, Linear, and hundreds of others are available through the same Composio Connect setup. Each new integration compounds what Hermes can do for you.
  • Build workflows across tools: Once multiple apps are connected, Hermes can chain actions together — turn an email into a calendar invite, a Slack message into a Linear ticket, or a meeting note into a follow-up draft.
  • Let it learn your patterns: The more you use Hermes, the better it gets at anticipating how you'd handle recurring tasks. Give it feedback on drafts and decisions, and it will adapt.

FAQ

Frequently asked questions

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

Yes, you can. Hermes 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 Listclean tools.

Yes, absolutely. You can configure which Listclean 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.

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 Listclean data and credentials are handled as safely as possible.
