U2 MCP Server

Connect Claude to your Universe/UniData database using natural language. u2-mcp is an MCP server that lets AI assistants like Claude query and interact with Rocket Universe and UniData MultiValue databases. Ask questions in plain English and get real answers from your data. Its 21 documented tools cover knowledge, record, file. It runs locally over stdio via the published package.

People connecting database tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install U2 MCP Server

before you install - you'll need

Set U2_HOST, U2_USER, U2_PASSWORD, U2_ACCOUNT, U2_KNOWLEDGE_PATH, U2_SERVICE, U2_HTTP_HOST, U2_HTTP_PORT, U2_AUTH_ENABLED, U2_AUTH_ISSUER_URL, U2_IDP_PROVIDER, U2_IDP_DISCOVERY_URL before connecting.

Claude Code

claude mcp add bpamiri-u2-mcp -- uvx u2-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "bpamiri-u2-mcp": {
      "command": "uvx",
      "args": [
        "u2-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.
