Analyze and optimize PostgreSQL queries for OLTP and OLAP workloads with AI-assisted performance tuning, indexing strategies, and execution plan analysis.

Official MCP server providing read-only access to PostgreSQL databases with schema inspection and query capabilities

The official InfluxData MCP server for InfluxDB 3 (Core, Enterprise, Cloud Dedicated, Clustered, and Cloud Serverless). It lets LLMs run SQL queries, write line-protocol data, inspect databases and measurement schemas, manage databases and tokens, and check cluster health over the Model Context Protocol.

The official SingleStore MCP server (singlestore-mcp-server) that lets AI assistants manage SingleStore from natural language — running SQL on a workspace, inspecting organizations, workspace groups, and workspaces, managing starter workspaces, notebooks, scheduled jobs, and Stage files — with no API keys required thanks to browser-based OAuth.

Read and write any local SQLite database from Claude — get database info, list tables, inspect schemas, create/read/update/delete records, and run raw SQL queries — with the MCP SQLite server that connects to any `.db` file you specify.

Query and explore your Metabase instance from Claude — list dashboards and cards, retrieve and execute saved questions, run SQL queries, export large result sets, and search across all Metabase resources — with the Metabase MCP server optimized for 90% token reduction.

Connect Claude to Teradata — list databases and tables, inspect DDL, run SQL queries, preview data, analyze column quality, and explore DBA diagnostics — with the official Teradata MCP server supporting optional ML tool expansion via the teradataml Python package.

Connect Claude to a local or in-memory Turso/libSQL database — query, insert, update, delete, and manage schemas with nine dedicated tools — using the official MCP server built into the Turso CLI with the `--mcp` flag.

Connect Claude to MotherDuck and DuckDB — run SQL queries and explore databases, tables, and columns — with the official MotherDuck Model Context Protocol server.

SpotDB local MCP server that exposes an ephemeral DuckDB sandbox for AI agents to upload CSV data, run guarded SQL queries, and explore datasets without touching production databases.

An MCP server from the official Couchbase-Ecosystem org that lets LLMs interact directly with Couchbase clusters — running SQL++/N1QL queries, performing document CRUD, discovering schema and data models, and analyzing query performance, with a read-only mode enabled by default.

MCP server for querying a local DuckDB database file from Claude through a single SQL query tool, with optional DuckDB-native read-only mode.

Official MariaDB MCP server for schema inspection, read-only SQL, optional database creation, and vector-store search against MariaDB databases.

SQLAlchemy-backed MCP server for exploring relational databases, inspecting schemas and relationships, and executing SQL queries from Claude.

PostgreSQL MCP server from Crystal DBA for schema inspection, SQL execution, EXPLAIN plans, index tuning, top-query analysis, and database health checks with configurable restricted or unrestricted access.

Official StarRocks MCP server for SQL execution, database exploration, StarRocks resource templates, system information, table/database overviews, and Plotly chart generation.

Token-efficient database MCP server for PostgreSQL, MySQL, MariaDB, SQL Server, and SQLite.

Open source MCP server and tool framework from Google for connecting AI agents, IDEs, and applications to databases through prebuilt or custom database tools.

MCP server for connecting Claude to MySQL databases with schema inspection, SQL query execution, SSH tunnel support, multi-database mode, and configurable write-operation controls.

Apache-2.0 dbt engine for transforming warehouse data with SQL models, Jinja, YAML configs, tests, documentation, lineage, metadata, and build artifacts.

MIT-licensed embedded analytical SQL database for local OLAP workloads, data files, notebooks, Python and R clients, extensions, and single-file analytics workflows.

Connect Claude to ClickHouse for read-only SQL exploration, schema discovery, and safe analytics workflows.

Source-backed rules for reviewing AI-generated database access code for SQL injection before merge, covering parameterized queries, identifier handling, ORM safety, dynamic query construction, least-privilege access, and privacy-safe test evidence.

Connect Claude to your Tinybird workspace — query real-time data sources, run text-to-SQL, call published API endpoints as tools, explore datasources, and analyze analytics data — with the official Tinybird hosted MCP server.

PostToolUse hook that detects writes to migration, schema, and SQL files then runs framework-specific status checks — runs knex migrate:status for Node.js projects and python manage.py showmigrations for Django projects.

Expert database architect and optimizer specializing in SQL, NoSQL, performance tuning, and data modeling

Build JavaScript and TypeScript apps with Bun, an all-in-one toolchain that replaces Node.js, npm, a bundler, and a test runner with one fast binary that executes TypeScript directly.

Open-source observability platform purpose-built for AI agents, with OpenTelemetry-native tracing, plain-English signals, an evals SDK and CLI, SQL dashboards, dataset annotation, and MCP/CLI access, self-hostable with Apache-2.0 SDKs for Python and TypeScript.

Official AWS Labs MCP server for AWS CloudTrail that lets AI assistants query account activity for security investigations, compliance auditing, and operational troubleshooting via Event History and CloudTrail Lake SQL.
