How to Connect Google Sheets to Hermes

Query your Google Sheets data directly from Hermes using Sequel’s MCP server. Ask questions in plain English, with no SQL, no dashboards, and no context switching.

Short answer

Connect Google Sheets to Sequel, then add Sequel's MCP server to Hermes using the config on this page. Hermes can then query your live Google Sheets data in plain English, with no connector code and no CSV exports. Both steps take a few minutes.

Example prompts

Everything you can ask Hermes about your Google Sheets data.

Ask in plain English — Sequel translates it into a Google Sheets query, runs it, and Hermes hands back the answer. No SQL, no dashboards, no CSV exports.

What you can ask Hermes
  • What sheets are in this spreadsheet?
  • Show me the first 50 rows from the Sales sheet
  • Add a new row to the Leads sheet with name John and email john@example.com
  • What are the column headers in the Inventory sheet?
  • Update cell B2 in the Budget sheet to 5000

How it works

Three steps to get started

1

Connect Google Sheets to Sequel

In your Sequel dashboard, go to Connections and add Google Sheets. Sequel handles authentication and schema discovery automatically.

2

Add Sequel to the agent

Copy the Sequel MCP configuration into Hermes's settings file (shown below). Swap in your API key from Settings → API Keys.

3

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.

Why Hermes

What Hermes does with your Google Sheets data

An agent that grows into a data analyst

Hermes runs on your own hardware and gets better the more you use it. Point it at Sequel and it gains a durable new skill: answering data questions across your databases, warehouses, and SaaS tools in plain English.

One server, every source, joined on the fly

Sequel connects to databases, warehouses, product analytics, and ad platforms. Ask Hermes to line up Stripe revenue against Google Ads spend, or GA4 sessions against your Postgres signups, and the join happens at query time with no upstream data model.

Scope the tools, keep the keys safe

Hermes supports per-server tool filtering with include and exclude lists in its YAML config, so you choose exactly which Sequel tools the agent can call. Sequel runs read-only by default, and your database credentials stay encrypted in Sequel, never in the Hermes config.

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"

Install

Install Google Sheets MCP in Hermes

Pick your app and Sequel installs itself: a one-click link where the client supports it, that client’s own few steps where it doesn’t. Every route signs in with your Sequel account over OAuth, so there is no API key to copy and nothing to keep in sync.

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.

How do I add Sequel to Hermes?

Add a `sequel` entry under `mcp_servers` in `~/.hermes/config.yaml` with Sequel's URL and your API key as an Authorization header, then run `/reload-mcp` in Hermes (or restart it). The Sequel CLI can write the config for you with `sequel install hermes`.

Which data sources can Hermes query through Sequel?

Any source you've connected in Sequel: PostgreSQL, MySQL, ClickHouse, BigQuery, Snowflake, Google Analytics, Search Console, Google Ads, Meta Ads, HubSpot, Stripe, and more. Hermes can only reach the connections your organization has set up.

Is Sequel a remote MCP server or a local command?

Remote. Sequel is hosted at https://api.sequel.sh/mcp, so in Hermes you configure it as an HTTP server with a `url` and an Authorization header, rather than a local stdio `command`.

Can I limit which Sequel tools Hermes can use?

Yes. Hermes supports per-server `tools` filtering with include and exclude lists in `config.yaml`. You can expose only the read and query tools you want a given agent to have.

How do I connect a Google Sheet?

Click 'New Connection', select Google Sheets, paste the URL of your Google Sheet, then click 'Connect with Google'. After authorising, Sequel verifies it can access that spreadsheet and creates the connection. One connection per spreadsheet — add more connections for additional sheets.

Can Sequel write to my spreadsheet?

Yes. Sequel requests read and write access to Sheets. You can append rows, update cells, and add new sheet tabs through the AI chat. Sequel will only modify the spreadsheet when you explicitly ask it to.

Can I connect multiple spreadsheets?

Yes. Each Sequel connection represents one spreadsheet. Create multiple connections if you need to query data across several spreadsheets.

Does Sequel have access to all my Google Drive files?

No. Sequel only requests access to the Google Sheets API, scoped to the specific spreadsheet you connect. It cannot read, list, or modify any other files in your Google Drive.
