Today, I accomplished a significant milestone by building an MCP server for DayBy, a platform that enables developers to seamlessly share their progress. This server is particularly useful for those using Claude, Cursor, or any MCP client. The standout feature of this server is its robust local sanitization layer. This layer plays a crucial role in safeguarding sensitive information by stripping out API keys, private IPs, company names, and other confidential data prior to any network transmission.

The design follows a draft → review → publish workflow, ensuring that nothing gets published without explicit approval. This process adds an additional layer of security and control, allowing developers to confidently share their updates without the fear of inadvertently leaking sensitive information.

I built this server using TypeScript along with the MCP SDK. The server operates over stdio transport, which aligns well with the needs for performance and reliability in this context. TypeScript provided the static type checking needed to catch errors early, while the MCP SDK facilitated seamless integration with existing MCP clients.

Incorporating a local sanitization layer was a priority from the outset. By ensuring that sensitive data is cleansed locally, I can prevent any unintended leaks, offering peace of mind to developers and their organizations. This feature was inspired by the increasing demand for more secure options when sharing development progress in collaborative environments.

The draft → review → publish flow is another key part of the server's architecture. This workflow allows for meticulous oversight of the content being shared. Developers can draft their progress, review the sanitization output, and then decide whether or not to publish. This not only enhances security but also gives developers full control over their content.

My experience with integrating GitHub into similar projects also influenced the development of this server. The integration provides a streamlined way of managing code and sharing updates, which aligns well with the functionalities provided by the MCP server.

Having previously written about enhancing user experience and transitioning to AI-driven solutions, my focus on reliability and security in this project aligns with my ongoing interest in improving AI and development tools. By building this server, I'm contributing to more secure and efficient development workflows.

This project marks another step in my journey of creating tools that prioritize both functionality and security. As the landscape of development continues to evolve, I remain committed to delivering solutions that address the unique challenges faced by developers today.
