## 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 Close 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.

## TL;DR

### 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.

## Connect Close to Hermes

### Integrating Close 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
```

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

The Close MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Close account. It provides structured and secure access to your sales pipeline, so your agent can perform actions like creating leads, logging calls, sending SMS, managing tasks, and retrieving notes on your behalf.
- Lead creation and management: Instantly create new leads with company details and contact information, keeping your CRM fresh and organized without manual entry.
- Automated call logging: Have your agent log both inbound and outbound calls to specific leads, capturing call notes, durations, and recordings for seamless tracking.
- SMS communication: Direct your agent to send or log SMS messages with leads, enabling timely follow-ups and improved client engagement.
- Task management: Let your agent create tasks, set due dates, and track completion, making sure nothing slips through the cracks in your sales workflow.
- Note retrieval and analysis: Fetch notes by lead or date, so your agent can summarize past interactions, surface important insights, or prepare for upcoming calls.

## Conclusion

### Way Forward
With Close 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.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Close MCP?

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

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

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