Read: Query BigQuery Without Writing SQL

Your AI agent becomes a direct interface to your data warehouse. Ask questions in plain English and get answers from BigQuery tables across any project, dataset, and date range. The MCP server handles query generation and execution.

Your AI agent reads harmonized data across 500+ platforms. "Cost" in Google Ads and "spend" in Meta Ads resolve to the same field automatically.

Example prompts
"Show anomalies across all accounts" 2h → 40s
"CPL in New York vs. California?" 1h → 30s
"ROAS by campaign type, last 30 days" 45m → 15s
Works with Claude ChatGPT Cursor +5
Write actions
"Launch A/B test, $5K budget" 5 days → 20m
"Shift 20% of Display to PMax" 2h → 1m
"Pause all ad groups with CPA > $50" 30m → 10s
🛡 Every action logged · Fully reversible · SOC 2 certified
🚀 Write

Write: Create and Update BigQuery Objects Through Chat

Your AI agent doesn't just query BigQuery — it manages it. Create views, schedule queries, update table schemas, and run transformation jobs through natural language without opening the BigQuery console.

250+ governance rules enforce naming conventions, budget limits, and KPI thresholds. SOC 2 Type II certified.

⚠️ Monitor

Monitor: Watch Data Quality and Pipeline Health

Set up watches on data freshness, row counts, and query costs. Your AI agent monitors BigQuery pipelines continuously and flags anomalies before they affect downstream reports.

Automated weekly reports, anomaly flagging, and budget alerts — all from a single conversation. No more morning check-ins across 5 dashboards.

Monitor prompts
"Flag ad groups over 120% budget" 3h → 1m
"Weekly report: spend, CPA, anomalies" 3h → auto
"Which creatives are fatiguing?" 2h → 30s
Alerts sent to Slack, email, or your AI agent

The Closed Loop: Read → Decide → Write → Monitor

Your AI agent doesn't just query BigQuery — it manages it. Create views, schedule queries, update table schemas, and run transformation jobs through natural language without opening the BigQuery console.

Every phase runs through the same MCP connection. One protocol, all platforms, full governance. No switching between tools.

Challenge 1

Non-Technical Teams Blocked by SQL Requirements

THE PROBLEM

Marketing, finance, and operations teams need BigQuery data but can't write SQL. Every data request goes to the data engineering queue, adding days to analyses that should take minutes. Self-serve BI tools cover basic dashboards but can't handle complex ad-hoc questions.

HOW MCP SOLVES IT

Improvado's MCP server translates natural language into BigQuery SQL, executes it, and returns formatted results. Non-technical teams query terabytes of warehouse data in plain English — no SQL training, no ticket backlog.

Try asking
"Show ROAS across all 120 accounts"

Challenge 2

Cross-Project Queries Require Complex IAM Setup

THE PROBLEM

Data warehouses span multiple GCP projects — analytics, production, staging, marketing. Running queries across projects requires coordinating service account permissions and writing cross-project SQL that few team members understand.

HOW MCP SOLVES IT

Improvado manages BigQuery service account credentials and cross-project access centrally. AI agents can query across all authorized projects in a single question without understanding GCP IAM or cross-project SQL syntax.

Challenge 3

Runaway Query Costs Discovered After the Fact

THE PROBLEM

Teams writing ad-hoc BigQuery queries often scan far more data than needed, generating unexpected costs. Billing alerts trigger after the spend happens, and tracking which queries caused the overrun requires manual log analysis.

HOW MCP SOLVES IT

Improvado's MCP server estimates query costs before execution and applies configurable data scan limits. AI agents surface cost estimates with results, and monitoring watches flag expensive query patterns in real time.

Try asking
"PMax vs. Search ROAS for Q1?"

👥 Teams

One Framework. Five Roles. Zero Setup.

Same MCP connection, different workflows for every team member. Agency CEOs get portfolio health. Media Strategists get campaign QA. Analysts get cross-platform reports. Account Managers get auto-generated QBR decks. Creative Directors get performance-based briefs.

Each role asks in natural language. The MCP server handles the complexity — rate limits, auth, schema normalization, governance — behind the scenes.

Frequently Asked Questions

Does Google BigQuery have an MCP server?
+

Google has released experimental MCP tooling for BigQuery as part of its broader AI agent ecosystem. Improvado offers a hosted alternative — no local installation, pre-connected GCP projects, and BigQuery data available alongside 500+ other marketing and analytics data sources through the same MCP connection.

What BigQuery operations can I perform through the MCP server?
+

Read operations: querying tables and views, schema exploration, dataset browsing, query history, and cost analysis. Write operations: creating and updating views, scheduling queries, modifying table schemas, and triggering data transfers. Improvado translates natural language into BigQuery SQL automatically.

Which AI tools work with BigQuery through this MCP server?
+

Any tool supporting the Model Context Protocol — Claude Desktop, ChatGPT, Cursor, Windsurf, Gemini, and custom applications using MCP HTTP transport. Claude is most commonly used due to its native MCP support and strong SQL generation capabilities.

How does Improvado control BigQuery query costs?
+

Improvado applies configurable data scan limits per query, estimates costs before execution, and surfaces cost information with query results. Teams can set project-level or user-level spend limits that prevent runaway scans while still enabling flexible ad-hoc analysis.

Can I query BigQuery alongside other data sources through the same MCP?
+

Yes. Improvado connects 500+ data sources through the same MCP server. Teams can combine BigQuery warehouse data with real-time marketing platform data from Google Ads, Salesforce, HubSpot, and others — enabling unified analysis without data movement.

Is BigQuery data secure through the MCP server?
+

Yes. Improvado is SOC 2 Type II certified. GCP service account credentials are stored in an encrypted vault and never exposed to AI agents. All queries execute through Improvado's secure proxy with full audit logging. Column-level access controls can be configured to restrict sensitive data.
