Hackle MCP: experiments and feature flags from your AI app

Hackle's MCP server puts the Hackle Admin API within reach of your AI app: experiments, feature flags, remote config and messaging. A flag or config change can reach every user, so ContextGate lets you switch off the tools that make changes, have a policy warn before one goes through, and see each call in Activity.

Connect Hackle to Cursor, Claude or ChatGPT

  1. 1Click Connect Hackle free and sign in with your Hackle account.
  2. 2The tools appear after connecting, all on. Reading how an experiment is set up is low risk; changing a feature flag or a remote config value isn't. Switch off the tools that change them, or add a policy that warns first.
  3. 3Add ContextGate to your AI app as a connector or MCP server. The steps for each app are on the Works with page.
  4. 4Ask your AI app which feature flags are set up in Hackle, and Activity will show the call it made.

Experimentation tasks for your AI app

  • Review and set up experiments from your editor.
  • Manage feature flags while you ship the code behind them.
  • Change remote config values from a chat.
  • Work with Hackle messaging through the same Admin API.

Change control for flags and config

  • Switch off the tools that change flags or config, and your AI app can only look.
  • Warn or block with a policy before a change goes through.
  • Activity records every change made through ContextGate.

What you get with Hackle and ContextGate

  • Your AI apps can use HackleClaude, Cursor, ChatGPT and other AI apps reach Hackle through the one ContextGate connection you add to them.
  • You choose which tools they can useSwitch off any Hackle tool you don't want used. It's hidden from your AI apps and refused if called.
  • Every call is checked and recordedYour policies check each call (for example, personal data is hidden and secrets are blocked), and Activity keeps a record of it.

ContextGate sees only the tool calls that go through it, not your AI app's built-in tools or your chats.
