Sequel

How to Connect Amplitude to Hermes

Query your Amplitude 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 Amplitude to Sequel, then add Sequel's MCP server to Hermes using the config on this page. Hermes can then query your live Amplitude 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 Amplitude data.

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

What you can ask Hermes
  • What's the 7-day retention for users who signed up last month?
  • Show me the conversion funnel from signup to first paid action over the past 30 days.
  • Which onboarding step has the biggest drop-off?
  • How many users triggered 'Subscription Started' last week, by plan?
  • Daily active users for the past 90 days, segmented by platform.

How it works

Three steps to get started

1

Connect Amplitude to Sequel

In your Sequel dashboard, go to Connections and add Amplitude. 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's the 7-day retention for users who signed up last month?" — and get a real answer backed by live Amplitude data.

Why Hermes

What Hermes does with your Amplitude 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 Amplitude 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 Amplitude to Hermes?

You need two things: (1) connect Amplitude 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 Amplitude data directly.

What Amplitude data can Hermes access?

Hermes can access any data available through your Amplitude 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 Amplitude 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 Amplitude and generate an API key. Sign up free at sequel.sh — no credit card required. Then create a connection to Amplitude and generate an API key from Settings → API Keys.

Can I connect multiple Amplitude accounts?

Yes. Sequel supports multiple connections of the same type. If you have multiple Amplitude 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 Amplitude to Sequel?

Open Amplitude → Settings → Projects → [your project] → General, copy the API Key and Secret Key, pick your region (US or EU), and paste them into Sequel's Amplitude connector. Sequel uses HTTP Basic auth with these keys against Amplitude's read APIs — no OAuth dance required.

Which Amplitude region should I pick?

Use the region the project was created in. US projects live on amplitude.com; EU projects live on analytics.eu.amplitude.com. If queries return 401 or empty results, the region is almost always the culprit — switch it and re-test.

Can Sequel write or modify data in Amplitude?

No. The connector only ships read-only tools: list events, list event properties, get chart, funnel report, retention report, and event segmentation. There is no write endpoint exposed to the agent, so Sequel cannot create events, charts, or cohorts on your behalf.

Do you support saved charts and dashboards?

Yes — if you already built a chart in Amplitude, share its chart ID with Sequel and it will pull the result via the Dashboard REST API, then re-segment or compare it conversationally without you re-creating it.
