Builders on cloud instances can now use Retool's MCP server to build apps. Apps are built using React and use Retool's updated app builder. Connect the MCP server to Claude, ChatGPT, Codex, Cursor, Kiro, or another agentic coding environment, and describe the app you want to build. Retool's building agent generates the app and returns a preview link. Publish and manage the app from the app builder.

Beyond initial generation, you can also use the MCP server to:

• Continue building or iterating on an existing app.
• Monitor active builds and view past agent activity.
• Review function runs that require human approval.
• Inspect or read the files of an existing app.
• Cancel a failed or in-progress build.

App building tools require the user to be a builder, and the builder must authorize the mcp:write scope. Refer to the tools reference for the full list.

Retool now supports an MCP server, which enables you to interact with your Retool organization from your chosen agentic environment.

Retool's MCP server currently supports tools that help you manage your organization and its users. For example, you can use the MCP for the following use cases:

• Write queries against resources to power data analysis.
• Bulk-invite users or manage pending invites.
• Audit the users who have access to your organization.
• Inspect organization and resource environment configurations.
• List all connected resources and see their configuration.

Refer to the tool reference for the full list.

Retool is actively adding additional tools that expand the capabilities of the MCP server to include additional Retool functionality, including app building.
