What is the Cube.dev MCP Server?
Connect your Cube.dev instance to any AI agent to bridge the gap between natural language and your data warehouse. This server allows your agent to interact with Cube's semantic layer, ensuring consistent metrics and high-performance data retrieval.
What you can do
- Data Querying — Execute complex REST API queries using
load_queryto fetch aggregated data with measures, dimensions, and filters. - SQL Inspection — Use
get_sqlandexecute_cube_sqlto debug or run raw queries against the SQL API for deep data investigation. - Metadata Exploration — Retrieve cube definitions, views, and segments via
get_metato understand your data model without leaving the chat. - Performance Management — Trigger and monitor background pre-aggregation builds with
trigger_pre_aggregation_jobto ensure your dashboards stay fast. - Cloud Management — List deployments and environments if using Cube Cloud to manage your infrastructure context.
How it works
- Subscribe to this server
- Provide your Cube API URL and Secret Token
- Start asking questions about your data metrics and model structure
Who is this for?
- Data Engineers — quickly verify data models and trigger cache refreshes via CLI or AI interface.
- Analytics Engineers — debug generated SQL and inspect metadata to ensure metric consistency.
- Product Managers — get instant answers to data questions by letting the AI query the semantic layer directly.

Cube.dev in Mastra AI
Cube.dev and 4,000+ other MCP servers. One platform. One governance layer.
Teams that connect Cube.dev to Mastra 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.

Why teams choose Vinkius for Cube.dev in Mastra AI
The Cube.dev 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 15 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.

How Vinkius secures
Cube.dev for Mastra AI
Every tool call from Mastra AI to the Cube.dev MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Can I see the exact SQL that Cube generates for a specific query?
Yes. You can use the get_sql tool. By providing the query JSON, the agent will return the generated SQL string, which is perfect for debugging or verifying your data logic.
How do I refresh the data cache or pre-aggregations using the AI?
You can use the trigger_pre_aggregation_job tool. You can specify which cubes or data sources to target, and the agent will initiate the background build process for you.
Is it possible to explore the available measures and dimensions?
Absolutely. Use the get_meta tool to fetch all metadata. This allows the AI to understand what data is available to be queried, including views and segments.
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.
