Metabase AI Assistant — Model Context Protocol (MCP) Server

Metabase AI Assistant is an enterprise-grade Model Context Protocol (MCP) server that connects Large Language Models (LLMs), AI coding assistants, and automated data workflows directly to your Metabase Business Intelligence instance.

Featuring 152 dedicated tools, native dbt Metadata & Metrics Auto-Syncer, Metabase to dbt Reverse Lineage Exposures, dbt-Smart Question Creator, Lightdash Code-as-BI YAML-to-Dashboard generation, Cube.js-style Pre-aggregations & Multi-Hop Lineage Joins, Omni.co Controlled Semantic-to-YAML bridge, autonomous self-healing SQL execution, full-scale dashboard architecting, proactive anomaly detection, query index advisory, zero-leak PII masking, and strict security guardrails. Works seamlessly with Claude, Cursor, ChatGPT, Gemini, and Google Antigravity.

Core Architectural Highlights

Metabase AI Assistant transforms standard AI interfaces (Claude Desktop, Cursor, VS Code, ChatGPT, Gemini, automated agent frameworks) into full-fledged Metabase power users:

1. dbt Deep Scanning & MetricFlow Integration (`dbt_project_scan_deep`): 9-tier architectural classification, doc('...') resolution, and catalog.json table/column profiling.
2. Cube.js Multi-Hop Lineage Joins (`dbt_lineage_joins_graph`): Resolves shortest join paths via Dijkstra Min-Heap algorithms with 3-color DAG cycle detection.
3. Cube.js Pre-Aggregation & Rollup Advisor (`dbt_semantic_preagg_advisor`): Generates multi-dialect Materialized View DDLs (Postgres, BigQuery, Snowflake, ClickHouse, DuckDB, Redshift, MySQL) with HyperLogLog distinct counts.
4. Lightdash Code-as-BI Dashboard Builder (`dbt_build_dashboard_from_yaml`): Translates meta.metabase and meta.lightdash formatting options into collision-free 24-column Metabase Dashboards.
5. Omni.co Controlled Semantic-to-YAML Exporter (`dbt_semantic_export_yaml`): Serializes approved business rules into clean dbt schema.yml / semantic_models.yml code blocks.
6. Autonomous Self-Healing SQL Engine (`ai_sql_execute_and_heal`): 3-iteration automated error-recovery loop for resilient querying.
7. Zero-Leak Enterprise PII Masker: Real-time sanitization of emails, phone numbers, national IDs, credit cards, IP addresses, and tokens.

Next-Gen Autonomous Features (v5.1)

1. dbt Architectural Hierarchy & Source Prioritization

$$\mathbf{Gold\;Marts\;(fct\_,\;dim\_,\;rpt\_)} \;\gg\; \mathbf{Silver\;(int\_)} \;\gg\; \mathbf{Bronze\;Staging\;(stg\_)}$$

• dbt_inspect_models: Parses dbt manifest.json and MetricFlow semantic models.
• dbt_prioritize_sources: Dynamically routes natural language questions to pre-aggregated, tested dimensional and fact tables.

2. Governance-First Semantic Memory (No Silent Learning, No Hard-Deletes)

• semantic_memory_propose: Proposes a business rule in PENDING_APPROVAL status.
• semantic_memory_approve: Explicitly activates the rule with required data steward comments.
• semantic_memory_deprecate: Safely soft-archives rules with mandatory audit reasons (DEPRECATED).
• semantic_memory_restore: Instantly restores archived rules.
• semantic_memory_list: Lists all rules with complete audit history and timestamps.

3. Autonomous Self-Healing SQL Engine (ai_sql_execute_and_heal)

• Catches syntax errors, Levenshtein-distance column misspellings, missing GROUP BY clauses, and dialect quirks across Postgres, MySQL, BigQuery, Snowflake, and SQLite.
• Preserves fix history in _provenance.healing_trail.

Metabase Version Compatibility

Metabase AI Assistant provides backward and forward compatibility across all major Metabase architectures:

Quick Start & Installation
