OpenViking MCP Server

A lightweight MCP (Model Context Protocol) server that connects to a running OpenViking server via HTTP, exposing its context database capabilities to Claude Desktop and other MCP clients.

No native compilation required -- only depends on httpx and mcp.

Prerequisites

  • Python 3.10+

  • A running OpenViking server (openviking-server on port 1933 by default)

Related MCP server: miniMCP
