Get data answers while you decide what to build

Overview

The Hex MCP connector lets Spark query your Hex workspace through conversation. Ask a data question while you plan and Spark opens a Hex Thread against your connected data sources, returning an answer grounded in live data. Each user connects their own Hex account, and access follows that account's permissions.

Ask data questions in plain language

Ask Spark a question about your product data and it starts a Hex Thread against your connected data sources. The answer comes back into the conversation, ready to use in the spec or brief you're writing.

Iterate on the analysis

Follow-up questions continue the same Hex Thread, so you can refine an analysis step by step without starting over. You can also pull the findings from an existing Thread into specs, briefs, or post-launch evaluations.

Find Hex projects

Ask Spark to find a Hex project by name or topic and it searches your workspace, surfacing the matching projects. Check what analysis already exists before commissioning new work.

Scoped to your Hex permissions

The connector uses your existing Hex account permissions. Hex workspace admins can restrict which data connections the integration can reach under Settings → Integrations → Agent integration data connection access.

Setup

Any Spark user can connect Hex. Connectors are set up per user, and no admin setup is required in Productboard. On the Hex side, the MCP server requires a Team or Enterprise plan and an Explorer workspace role or higher.

1. From any Spark chat, click Integrations → Add connectors.
2. Find Hex in the list, click its name to review details, then click Connect.
3. Sign in on Hex's page, review what Spark can access, and grant access. You'll return to Productboard with the connection active in every Spark chat.
