How it works

Three steps to get started

Connect HubSpot to Sequel

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

Add the MCP config

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

Ask Codex about your data

Restart Codex and start asking questions. "How many open deals do we have, broken down by stage and owner?" — and get a real answer backed by live HubSpot data.

Configuration

Add Sequel to Codex

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

~/.codex/config.yaml

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

Example prompts

Questions you can ask Codex

“How many open deals do we have, broken down by stage and owner?”

“What's the win rate by lead source for deals closed this quarter?”

“Show me deals over $50k that have been in 'Proposal Sent' for more than 30 days.”

“Average time-to-close for deals in the Enterprise pipeline this year.”

“Which companies in the Healthcare industry have no contacts in 'Lifecycle: Customer'?”

“List the 20 most recently created tickets with their priority and pipeline.”

“How many tickets did we close last week, by category?”

“Which contacts haven't been touched in 90 days but are in an open deal?”

“Show me the conversion rate from 'Marketing Qualified Lead' to 'Sales Qualified Lead' this year.”

Frequently asked questions

How do I connect HubSpot to Codex?

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

What HubSpot data can Codex access?

Codex can access any data available through your HubSpot 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 HubSpot data sent to Codex's servers?

Query results are returned to Codex 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 HubSpot and generate an API key. Sign up free at sequel.sh — no credit card required. Then create a connection to HubSpot and generate an API key from Settings → API Keys.

Can I connect multiple HubSpot accounts?

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