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 Openperplex 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 Openperplex 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 Openperplex

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

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

5. Done!

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

The Openperplex MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Openperplex account. It provides structured and secure access to powerful web search, real-time content streaming, and website analysis tools, so your agent can perform actions like global searches, web content extraction, document interrogation, and live website analysis on your behalf.

  • Powerful global search and filtering: Instantly ask your agent to search across the web or custom document sets with advanced query options, filters, and field selection for tailored results.
  • Live streaming search results: Enable your agent to provide real-time updates on search queries, perfect for monitoring changing information or tracking trends as they unfold.
  • Website content extraction: Have your agent pull main text, full markdown, or screenshots from any publicly accessible website, making it easy to analyze, summarize, or archive web content.
  • Natural language querying of online documents: Let your agent interrogate web-hosted content directly using natural language, giving you precise answers and insights from any URL.
  • Custom document search and analysis: Empower your agent to search specific document collections, apply filters, and surface relevant content for research, competitive analysis, or data gathering tasks.

Supported Tools & Triggers

Tools
Custom SearchTool to perform a custom search with optional filtering and field selection.
Custom Search StreamTool to perform custom streaming search.

Way Forward

With Openperplex 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 Openperplex MCP?

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

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

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