Compatible with every major AI agent and IDE
What is the ToolJet MCP Server?
Connect your ToolJet workspace to any AI agent to interact with your internal databases and automate business logic through natural language.
What you can do
- Database Exploration — List all available tables within your ToolJet Database to understand your data structure.
- Advanced Querying — Execute SQL SELECT queries on your tables to retrieve specific records, filter data, and generate insights.
- Data Entry — Insert new rows into your database tables directly from the chat interface using structured JSON data.
- Workflow Automation — Trigger complex ToolJet Workflows via webhooks, passing custom payloads to start automated business processes.
How it works
- Subscribe to this server
- Enter your ToolJet API Key (and optional Host URL for self-hosted instances)
- Start managing your internal data and workflows from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Developers — Quickly query internal databases or trigger CI/CD workflows without leaving the code editor.
- Operations Teams — Update records or start business processes using natural language instead of complex UIs.
- Data Analysts — Explore ToolJet Database tables and run ad-hoc queries to verify data integrity.

Why teams choose Vinkius for ToolJet in Mastra AI
The ToolJet MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 4 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in Mastra AI only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

* Every MCP server runs on Vinkius-managed infrastructure inside AWS - a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts optimized for native MCP execution. See our infrastructure
How Vinkius secures
ToolJet for Mastra AI
Every tool call from Mastra AI to the ToolJet MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Can I perform complex SQL joins using this server?
Yes, the query_table tool allows you to execute SQL queries. As long as the tables exist in your ToolJet Database and your organization ID is correct, you can perform SELECT statements including joins and filters.
How do I trigger a specific automation I built in ToolJet?
You can use the trigger_workflow tool. You will need the workflow_id and can optionally provide a JSON payload to pass data into the workflow's entry point.
Can I see the list of all my database tables?
Absolutely. Use the list_tables tool to retrieve a complete list of all tables currently configured in your ToolJet Database workspace.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
