How it works
Three steps to get started
Connect MCP Server to Sequel
In your Sequel dashboard, go to Connections and add MCP Server. Sequel handles authentication and schema discovery automatically.
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.
Ask Hermes about your data
Restart Hermes and start asking questions. "What tools does this MCP server provide?" — and get a real answer backed by live MCP Server 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"Install
Install MCP Server 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 MCP Server to Hermes?
You need two things: (1) connect MCP Server 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 MCP Server data directly.
What MCP Server data can Hermes access?
Hermes can access any data available through your MCP Server 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 MCP Server 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 MCP Server and generate an API key. Sign up free at sequel.sh — no credit card required. Then create a connection to MCP Server and generate an API key from Settings → API Keys.
Can I connect multiple MCP Server accounts?
Yes. Sequel supports multiple connections of the same type. If you have multiple MCP Server accounts or properties, add each as a separate connection in Sequel. Hermes will be able to query all of them.
