Refix MCP

Use Refix from your AI assistant.

Ask Refix to investigate a business question, pursue an ongoing goal, or catch you up on what it found, directly from Claude, ChatGPT, and other MCP clients.

Why did trial-to-paid conversion drop last month?

Trial starts held steady. The drop came after activation, where fewer new users reached the first shared report.

What assistants can do

Bring Refix into the conversation you already started.

Your assistant handles the conversation. Refix handles the business investigation, using the data and context already connected to your workspace.

  • Investigate a question

    Ask in your own words. Refix follows the evidence across the connected sources in your workspace.

  • Keep a goal moving

    Create and manage watchers that pursue an outcome over time and report useful findings.

  • Catch up on findings

    Read watcher alerts, reminders, and other proactive updates without starting another investigation.

Example prompts

Ask about the outcome, not the table.

Refix chooses the relevant connected sources, tests likely explanations, and returns the evidence behind its answer.

  • “Investigate why trial-to-paid conversion dropped last month.”
  • “Find the biggest revenue leak in our customer journey and recommend what to test next.”
  • “Compare retention across acquisition channels and explain what drives the difference.”
  • “Watch failed payments and tell me when a pattern needs attention.”
  • “What has Refix found about our growth goals this week?”
  • “Dig deeper into the latest Refix finding and show me the supporting evidence.”

Questions about Refix MCP.

Connecting an assistant and understanding what it can access.

Talk to a human

Does Refix work with Claude?

Yes. Refix is listed in Claude's connector directory. Add it in Claude under Settings > Connectors, or add the hosted endpoint as a custom connector. It works in claude.ai, Claude Desktop, and Claude Code.

Does Refix work with ChatGPT?

Yes. Refix is available as a ChatGPT plugin. Open the Refix listing in ChatGPT, add it, then sign in to Refix and choose a workspace.

How does an assistant connect to Refix?

Add the hosted MCP endpoint. Refix uses OAuth with PKCE and dynamic client registration. You sign in, choose a workspace, and approve access in your browser.

Does the Refix MCP connection use API keys?

No. The connection uses OAuth with PKCE. Never paste Refix credentials, integration credentials, or payment details into an assistant chat.

Can the assistant change data in a connected source?

No. The MCP connection does not write directly to connected sources. A proposed action in a tool such as Linear or Jira requires a person to review it in Refix.

Which MCP requests use workspace credits?

Investigations and watchers use workspace credits. Reading workspace context and existing findings does not use credits.

Can I connect a self-hosted or dedicated Refix workspace?

Not currently. The hosted MCP endpoint is available for Refix cloud workspaces on the shared service.

Can one connection access more than one workspace?

No. One connection is approved for one workspace. Connect Refix again when you need to use a different workspace.
