How to integrate Grok MCP with Hermes

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 Grok 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 Grok 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 Grok

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

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

5. Done!

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

The Grok MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Grok account. It provides structured and secure access to Grok's text, image, video, embedding, model, and account capabilities, so your agent can generate responses, create media, produce embeddings, browse available models, and verify account access on your behalf.

  • Text and multimodal responses: Have your agent generate focused responses from text or structured multimodal input, with optional reasoning and search.
  • Image creation: Direct your agent to create one or more images from a detailed text prompt using an available Grok image model.
  • Video generation and tracking: Let the agent start a video from a text prompt, optionally use an image as context, and check its progress later.
  • Text embeddings: Instruct your agent to turn one or more text inputs into vector embeddings for search, matching, or classification tasks.
  • Model and account checks: Have your agent review available models and pricing details, verify the connected account, and inspect API key permissions or blocking status.

Way Forward

With Grok 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.

TOOLS

Supported Tools

Every Grok action and event your agent gets out of the box.

Create Embeddings

Create vector embeddings for one or more text inputs with an xAI embedding model.

Create Response

Generate a bounded, non-streaming Grok response from text or structured multimodal input, with optional reasoning, search, and function or web-search tools.

Generate Image

Generate one or more images from a text prompt with an xAI image-generation model.

Generate Video

Start asynchronous xAI video generation from a text prompt, optionally conditioned on an image, and return a request ID for status checks.

Get API Key Info

Inspect the connected xAI API key's identity, wildcard or granular ACLs, and key or team blocking state.

Get Current Account

Verify the connected xAI credential and return the caller, team, zero-data-retention status, and key blocking state.

Get Video

Check an asynchronous xAI video request.

List Models

List models available to the connected xAI key, including model IDs and published pricing metadata needed to choose a model for other tools.

FAQ

Frequently asked questions

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

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 Grok tools.

Yes, absolutely. You can configure which Grok 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.

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 Grok data and credentials are handled as safely as possible.
