"k6" matching MCP servers:

SchemaBrain is an MCP server that sits between AI agents (Claude, Cursor, Windsurf) and your SQL database as a read-only trust + intelligence layer. The agent never writes SQL — 12 tools compile it from definitions you control, PII and secret categories are refused before the query runs, and every call lands in a tamper-evident (SHA-256-chained) audit log. Postgres today.

A read-only MCP server that provides tools to read, list, and inspect secrets from HashiCorp Vault's KV secrets engine (versions 1 and 2) using a Vault token.

Enables comprehensive management of AWS S3 Tables including table bucket, namespace, table CRUD, metadata, maintenance, and data import operations through natural language.

An MCP server that grounds KQL queries on your actual schema and expertise, helping AI assistants generate validated, accurate queries for Kusto databases.

Enables users to manage company departments, employees, expenses, and performance ratings through a natural language interface in Claude Desktop. It features 12 specialized tools for comprehensive CRUD operations and AI-powered organizational analysis using Google Gemini.

A read-only Postgres MCP server that parses SQL to block write statements and prevents bypasses by refusing connections with write privileges.

A Model Context Protocol (MCP) Server that allows AI models to securely interact with data hosted in Azure Database for PostgreSQL. It enables natural language querying, schema exploration, and data management through MCP clients like Claude Desktop and Visual Studio Code.

Enables LLMs to manage file-based knowledge bases with dual storage (Markdown + SQLite). Supports creating, searching, and organizing articles across multiple knowledge bases with full-text search capabilities.

A comprehensive local offline MCP server with over 300 tools for file operations, office documents, PDFs, code execution, databases, web browsing, memory, and cognitive functions, designed to work offline except for web search and email.

Enables controlled access to Oracle/PLSQL databases, allowing querying, schema browsing, and optional PL/SQL execution with per-connection safety controls.

Enables Claude to query Neo4j databases using natural language, running on Cloudflare Workers for serverless deployment.

Enables heavy computation and data processing tasks in Claude Desktop, including complex SQL operations, large-scale data transformations, and resilient batch processing with automatic retry mechanisms.

A Knowledge Graph MCP server optimized for LLM context efficiency through compact JSON and SQLite persistence. It enables full graph management including node/edge CRUD operations, full-text search, and subgraph traversal.

A Model Context Protocol server integrating developer tools including Git control, document conversion, remote SSH execution, database operations, and utilities for automation and development productivity.
