Local-YDB unofficial mcp server: Give AI agents direct access to your YDB database

YDB is a powerful distributed database, but connecting it to your AI coding workflow shouldn't require manual queries or context switching. The Local-YDB unofficial mcp server bridges that gap by exposing YDB database operations directly to Claude, Cursor, and other MCP-compatible AI agents.

What It Does

This MCP server acts as a standardized interface between AI agents and YDB instances—local or remote. Instead of copy-pasting connection strings or manually explaining your schema, you can let your AI assistant inspect tables, run queries, debug data issues, and manage database state directly through a clean tool interface.

The server unlocks capabilities like schema inspection, query execution, transaction management, and debugging workflows. Your AI agent can now understand your actual database structure in real time rather than working from stale documentation or guesswork. This is especially valuable during development when you're iterating quickly and need your AI assistant to understand data relationships, spot migration issues, or generate accurate queries without hallucination.

How to Install

Install the server via npm:

npx -y @astandrik/local-ydb-mcp

Then add it to your Claude Desktop configuration (or equivalent for Cursor/Windsurf):

{
  "mcpServers": {
    "local-ydb-unofficial-mcp-server": {
      "command": "npx -y @astandrik/local-ydb-mcp"
    }
  }
}

Restart your client, and the server will be available to your AI agent immediately.

Real-World Use Cases

• Debug production data issues: Ask Claude to query a specific table, inspect recent records, and identify why a migration didn't apply correctly—without leaving your IDE.

• Generate schema-aware queries: Your AI assistant inspects actual table structure and generates correct queries instead of guessing at column names or types.

• Prototype database operations: Develop and test schema changes, write transaction logic, or validate data integrity with real-time feedback from your live database.
