Open-source service runtime configured by agents via WebMCP
Mantle is an innovative open-source framework designed for developers and businesses seeking to streamline service development. It enables users to convert business rules into typed schemas, views, procedures, and HTTP/MCP triggers, all through a browser-based interface. The platform's WebMCP-native Builder allows for designing and verifying services visually, making it accessible to both technical and semi-technical users. Once the design phase is complete, a coding agent can finalize the service for self-hosting or deployment. With its open-source core and live live OSS and Builder tools, Mantle promotes flexibility and community-driven development. Additionally, Mantle Cloud, currently in Internal Beta, hints at an upcoming cloud-hosted offering that aims to simplify deployment and scaling. Its unique approach of combining visual service design with agent-assisted coding positions it as a compelling solution for rapid development, automation, and custom service creation.
