概要

What is YDB MCP?

YDB MCP is a Model Context Protocol server for YDB, a distributed SQL database. It allows large language models (LLMs) that support MCP to interact with YDB databases through natural language, enabling AI-powered database operations.

How to use YDB MCP?

Install YDB MCP via uvx, pipx, or pip. Configure your MCP client with the server command and connection arguments (e.g., --ydb-endpoint, --ydb-database). Authentication can be anonymous, login/password, access token, or service account (requires the yandexcloud package for the latter). Examples for each method are provided in the README.

Key features of YDB MCP

  • Run SQL queries against any YDB database
  • Execute parameterized SQL queries with JSON parameters
  • Explain query execution plans
  • List directory contents and describe paths in YDB
  • Check the current status of the YDB connection
  • Supports building custom MCP servers by subclassing YDBMCPServer

Use cases of YDB MCP

  • Let an LLM explore and query a YDB database using natural language
  • Implement read-only, domain-specific database tools for an AI assistant
  • Build custom MCP servers that expose only the queries your application needs
  • Diagnose YDB performance by explaining query plans via AI

よくある質問

1

What authentication modes does YDB MCP support?

Anonymous (default), login/password, access token, and service account authentication. Service account requires the `yandexcloud` package installed separately.

2

What tools are included with YDB MCP?

Seven tools: `ydb_query`, `ydb_query_with_params`, `ydb_explain_query`, `ydb_explain_query_with_params`, `ydb_list_directory`, `ydb_describe_path`, and `ydb_status`.

3

Can I restrict which tools the LLM can access?

Yes. When building a custom server by subclassing `YDBMCPServer`, you can set the `generic_tools` class attribute to a subset of `YDBGenericTool` values or an empty set to disable all built-in tools.

4

What are the runtime dependencies for YDB MCP?

YDB MCP is a Python package available on PyPI. It depends on the MCP SDK and YDB client libraries. For service account authentication, the `yandexcloud` package is also required.

5

How do I configure YDB MCP for my client?

Provide the server command (`uvx ydb-mcp`, `pipx run ydb-mcp`, or `python -m ydb_mcp`) and arguments such as `--ydb-endpoint` and `--ydb-database`. Authentication arguments can be added as needed.
