THE BUILDER STUDIO · FROM IDEA TO REVIEW

AI Plugin
Builder Studio

Build a small tool. Make it useful. Bring it to the club.

Create MCP tools and reusable agent skills with a drag-and-drop block editor. Start with a recipe, try an example and prepare your work for administrator review. No code or provider key is needed for the low-code studio.

Open Builder Studio Create a builder account

Sign in to use your private workspace. All marketplace services are simulations; no purchases or payouts occur.

BLOCKS FIRST

Small blocks. Useful tools. Reusable skills.

Connect text operations to build an MCP tool, or arrange instructions, guardrails and examples into an agent skill. Button controls offer the same editing flow without dragging.

Skills download as standard SKILL.md instructions. Administrators review public releases; your private drafts stay yours.

Create and Test Plugins

Create simple text tools with restricted PHP expressions, JSON configuration and immutable versions. Test sample input in your private workspace before requesting a release.

Administrators can also generate draft code through a configured AI provider. Every draft follows the same validation and review process.

Deal Cards and Marketplace Drafts

Explain what your tool does, choose a category and attach it to a draft deal card. Only an administrator can release the plugin and publish its offer.

Prices are illustrative. Publication makes a released simulation available for members to activate and try.

A CLEAR PATH TO PUBLICATION

How to prepare an MCP plugin for review

  1. Create a builder account

    Register as a builder, or enable Builder Studio from your existing account. Your buyer workspace stays available.

  2. Draft and test a plugin

    Connect blocks in the low-code studio, save a plugin draft and run a test with sample text. Advanced builders can still write restricted PHP expressions or import .mcp.json packages.

  3. Accept terms and submit

    Accept the current publisher agreement and platform fee before submitting a tested version. If terms are not yet available, keep preparing your drafts.

  4. Prepare a deal card for review

    Attach your plugin to a draft deal card and submit it. An administrator reviews and releases the plugin and publishes its offer before members can activate it.

BEFORE YOU SUBMIT

Publisher Agreement Status

Your private studio shows the current agreement, platform fee and your acceptance status. Accept the published version before submitting a plugin or deal card. If no agreement is available, you can still create and test drafts.
