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 Pydantic AI?
Pydantic AI validates every ToolJet tool response against typed schemas, catching data inconsistencies at build time. Connect 4 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.
- —
Full type safety: every MCP tool response is validated against Pydantic models, catching data inconsistencies before they reach your application
- —
Model-agnostic architecture. switch between OpenAI, Anthropic, or Gemini without changing your ToolJet integration code
- —
Structured output guarantee: Pydantic AI ensures tool results conform to defined schemas, eliminating runtime type errors
- —
Dependency injection system cleanly separates your ToolJet connection logic from agent behavior for testable, maintainable code
ToolJet in Pydantic AI
ToolJet and 4,000+ other MCP servers. One platform. One governance layer.
Teams that connect ToolJet to Pydantic AI through Vinkius don't need to source, host, or maintain individual MCP servers. Every tool call runs inside a hardened runtime with credential isolation, DLP, and a signed audit chain.

| Infrastructure | Self-hosted | Sandboxed V8 isolates |
| Credential handling | Plaintext in config | Vault + runtime injection |
| Data loss prevention | None | Configurable DLP policies |
| Kill switch | None | Global instant shutdown |
| Financial circuit breakers | None | Per-server limits + alerts |
| Audit trail | None | Ed25519 signed logs |
| SIEM log streaming | None | Splunk, Datadog, Webhook |

Why teams choose Vinkius for ToolJet in Pydantic 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 Pydantic 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 Pydantic AI
Every tool call from Pydantic 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 Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your ToolJet MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
