About the server

A unified MCP gateway that gives MCP-compatible clients — Claude, Cursor, OpenClaw, and others — access to 100+ production-ready tools through a single endpoint, instead of installing and configuring a separate server per tool.

• Coverage — search, SEO/analytics, shopping, maps/travel, media, finance, and dev utilities.
• Single endpoint — one connection replaces dozens of individual MCP server configs, keeping client config and agent context manageable.
• Custom MCP Builder — turns any REST API into an MCP tool, so teams can extend the gateway with their own services.
