About Retool MCP Server
Connect your conversational assistant directly to the Retool ecosystem. This integration enables your AI to explore the organizational structure of your internal tools, auditing who has access to what, and reviewing which databases are connected.
Mastra's agent abstraction provides a clean separation between LLM logic and Retool tool infrastructure. Connect 7 tools through Vinkius and use Mastra's built-in workflow engine to chain tool calls with conditional logic, retries, and parallel execution. deployable to any Node.js host in one command.
What you can do
- Audit Applications — Ask your assistant to scan your Retool workspace (
list_apps) and drill down into the configuration of specific tools (get_app). Observe how tools are organized by requesting a view of the folder hierarchy (list_folders). - Manage Permissions & Users — Review the active members of your Retool organization (
list_users) and understand their access levels by listing the existing permission groups (list_groups). - Review DevOps & Infrastructure — Command the AI to inspect which data sources or APIs are wired into your operational stack (
list_resources), and list any active background automation tasks (list_workflows).
The Retool MCP Server exposes 7 tools through the Vinkius. Connect it to Mastra AI in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
