How it works

Three steps to get started

Ask Hermes about your data

Restart Hermes and start asking questions. "What sheets are in this spreadsheet?" — and get a real answer backed by live Google Sheets data.

Configuration

Add Sequel to Hermes

Place this in ~/.hermes/config.yaml and replace sql_your_api_key with a key from Settings → API Keys.

~/.hermes/config.yaml

mcp_servers:
  sequel:
    url: "https://api.sequel.sh/mcp"
    headers:
      Authorization: "Bearer sql_your_api_key"

Frequently asked questions

How do I connect Google Sheets to Hermes?

You need two things: (1) connect Google Sheets to Sequel in your Sequel dashboard under Connections, and (2) add the Sequel MCP config to Hermes using the setup shown above. Once both are done, Hermes can query your Google Sheets data directly.

What Google Sheets data can Hermes access?

Hermes can access any data available through your Google Sheets connection in Sequel. Use Sequel's search tool to discover available metrics and dimensions, then execute queries to pull the data you need.

Is my Google Sheets data sent to Hermes's servers?

Query results are returned to Hermes as context within your conversation. Only the data you explicitly ask about is retrieved. Sequel never stores your query results permanently — they exist only for the duration of the tool call.

Do I need a Sequel account?

Yes. You need a Sequel account to connect Google Sheets and generate an API key. Sign up free at sequel.sh — no credit card required. Then create a connection to Google Sheets and generate an API key from Settings → API Keys.

Can I connect multiple Google Sheets accounts?

Yes. Sequel supports multiple connections of the same type. If you have multiple Google Sheets accounts or properties, add each as a separate connection in Sequel. Hermes will be able to query all of them.
