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 Rev ai 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 Rev ai 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 Rev ai

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

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

5. Done!

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

The Rev ai MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Rev ai account. It provides structured and secure access to your speech-to-text workflows, so your agent can perform actions like transcribing audio, retrieving transcripts, managing custom vocabularies, and handling transcription jobs on your behalf.

  • Automated audio and video transcription: Effortlessly submit audio or video files for transcription, and let your agent monitor job progress until transcripts are ready.
  • Transcript and caption retrieval: Retrieve full transcripts in multiple formats or download caption files (SRT, VTT) for completed jobs—perfect for both review and publishing.
  • Custom vocabulary management: Enhance transcription accuracy by submitting and maintaining domain-specific vocabularies, including adding new terms and deleting unused sets.
  • Transcription job management: List, fetch, or delete transcription jobs by ID, making it easy for your agent to keep your workspace organized and up-to-date.
  • Real-time streaming transcription: Start live stream transcriptions for instant speech-to-text conversion, allowing your agent to process and react to spoken content in real time.

Way Forward

With Rev ai 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 Rev ai MCP?

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

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

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