Introduction

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 Ngrok 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 Ngrok 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 Ngrok

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

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

5. Done!

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

The Ngrok MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Ngrok account. It provides structured and secure access to your Ngrok tunnels and API keys, so your agent can perform actions like managing endpoints, listing tunnels, handling API keys, and auditing IP restrictions on your behalf.

  • Active tunnel and endpoint monitoring: Instantly list all active tunnels and endpoints in your Ngrok account, making it simple to track running services and public URLs.
  • API key management: Programmatically create, list, and delete API keys to securely manage who and what can access your Ngrok resources.
  • HTTPS edge configuration visibility: Retrieve a comprehensive list of all HTTPS edges to review and manage how Ngrok handles encrypted traffic.
  • IP restriction and policy auditing: List and inspect all IP restrictions and policy rules, helping you enforce access control and security best practices.
  • Detailed access audit trails: Fetch details about specific IP restrictions for security audits and compliance, ensuring you always know who can access your tunnels and APIs.

Supported Tools & Triggers

Tools
Create API KeyCreates a new api key for authenticating with the ngrok api.
Delete API KeyDelete an api key by its id.
Get IP Restriction DetailsThis tool retrieves detailed information about a specific ip restriction by its id.
List API KeysThis tool lists all api keys owned by the user.
List All EndpointsList all active endpoints on the ngrok account.
List HTTPS EdgesLists all https edges in your ngrok account.
List IP Policy RulesThis tool lists all ip policy rules associated with your ngrok account.
List IP RestrictionsThis tool retrieves a list of all ip restrictions configured on the ngrok account.
List Active TunnelsList all active tunnels in the ngrok account.

Way Forward

With Ngrok 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

What are the differences in Tool Router MCP and Ngrok MCP?

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

Can I use Tool Router MCP with Hermes?

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 Ngrok tools.

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

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