MCP server

A read-only Model Context Protocol server lets an AI system query the database directly: search_robots, search_site (robots, manufacturers, articles), get_article, get_robot, compare_robots, get_robot_claims, get_robot_sources, get_robot_prices, get_robot_availability, get_recent_changes, find_home_robots, find_robots_by_utility, find_robots_by_capability, find_programmable_robots, search_open_source_projects and get_methodology.

Every answer gives its sources, its dates and its level of evidence, flags outdated data, and wraps third-party quotes as untrusted data.

Address: https://vuntum.com/mcp (Streamable HTTP). Free, no key and no sign-up, 60 requests per minute per IP address. In Claude Code: claude mcp add --transport http vuntum https://vuntum.com/mcp. The setup for claude.ai, Claude Desktop, ChatGPT, Cursor and VS Code is in the server’s public repository.

The server is listed in the official MCP registry as com.vuntum/mcp.
