## 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 Captions 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.

## Also integrate Captions with

- [Claude Cowork](https://composio.dev/toolkits/captions/framework/claude-cowork)

## 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 Captions to Hermes

### Integrating Captions 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 Captions MCP server, and what's possible with it?

The Captions MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Captions account. It provides structured and secure access so your agent can perform Captions operations on your behalf.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `CAPTIONS_ADD_CAPTIONS` | Add Captions | Start an asynchronous job that transcribes and renders a selected caption style onto an uploaded or existing completed video. Use CAPTIONS_GET_VIDEO_STATUS to monitor the returned job, then CAPTIONS_DOWNLOAD_VIDEO when it completes. This call consumes paid Mirage credits and cannot be cancelled or deleted once submitted. |
| `CAPTIONS_DOWNLOAD_VIDEO` | Download Video | Download the MP4 content of a completed video job and return an offloaded file reference. Use CAPTIONS_GET_VIDEO_STATUS first to confirm the job is COMPLETE. |
| `CAPTIONS_GENERATE_SPEECH` | Generate Speech | Generate WAV speech synchronously from text using a known Mirage voice ID and return an offloaded audio file reference. This call consumes paid Mirage credits and cannot be cancelled or deleted once submitted. |
| `CAPTIONS_GENERATE_VIDEO` | Generate Video | Start an asynchronous Mirage Video 1 job that animates a portrait image using speech audio. Use the returned job ID with CAPTIONS_GET_VIDEO_STATUS. This call consumes paid Mirage credits and cannot be cancelled or deleted once submitted. |
| `CAPTIONS_GET_CAPTION_TEMPLATE` | Get Caption Template | Retrieve one caption style by ID, including its name and preview video URL. |
| `CAPTIONS_GET_VIDEO_STATUS` | Get Video Status | Retrieve the current state, progress, and error details for a video generation or captioning job. |
| `CAPTIONS_LIST_CAPTION_TEMPLATES` | List Caption Templates | Return one page of available caption styles, including names and preview video URLs. |
| `CAPTIONS_LIST_VIDEOS` | List Videos | Return one page of video jobs owned by the connected Mirage account, including each job's status and progress. |

## Creating MCP Server - Stand-alone vs Composio SDK

The Captions MCP server provides comprehensive access to Captions operations through Composio. Once connected, Hermes can perform all major Captions actions on your behalf using natural language commands.

## Conclusion

### Way Forward
With Captions 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 Captions MCP?

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

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

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