During April 2025, Yamao focused on stabilizing the Server-Sent Events (SSE) server startup process for the firecrawl/firecrawl-mcp-server repository. Addressing a reliability issue, Yamao implemented a missing app.listen call in the Express.js backend, ensuring the server could initialize correctly in SSE mode. The solution included robust port configuration using Node.js, defaulting to port 3000 with support for environment variable overrides to enhance deployment flexibility. Startup logs were added to improve observability and troubleshooting. This targeted bug fix, developed in TypeScript, increased the reliability of SSE endpoints and streamlined real-time client updates, reducing downtime and simplifying operational diagnostics.
