How to integrate Addresszen 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 Addresszen 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 Addresszen 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 Addresszen

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

4. Done. You're all set with a new Addresszen 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 Addresszen or request any Addresszen-related task. It will prompt you to authenticate and authorize access.

5. Done!

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

The Addresszen MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Addresszen account. It provides structured and secure access to real-time address autocomplete and verification services, so your agent can suggest accurate addresses, validate API keys, and resolve complete address details on your behalf.

  • Instant address autocomplete and suggestions: Enable your agent to quickly provide users with accurate address suggestions as they type, reducing input errors and saving time.
  • Address resolution and formatting: Let your agent resolve address suggestion IDs into full, deliverable US-format addresses for shipping, billing, or form completion.
  • API key validation and monitoring: Easily verify whether your Addresszen API key is active and usable before making further requests, ensuring seamless integrations.
  • Seamless address validation in workflows: Automate the process of checking and completing addresses, so your agent can support onboarding, checkout, or CRM data entry without manual review.

Way Forward

With Addresszen 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 Addresszen MCP server, the agents and LLMs can only access a fixed set of Addresszen tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Addresszen 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 Addresszen tools.

Yes, absolutely. You can configure which Addresszen 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 Addresszen data and credentials are handled as safely as possible.
