Porting an MCP Server from Go to Rust Using LLMs
A while ago there was a post about agentic development for a project. This is a follow-up, but in a slightly different, more practical direction. The task was an MCP service / KAG / GraphRAG in Go. After completion, it “unexpectedly” turned out that the project contained a fatal flaw in the shape of the letter G. So a deliberate decision was made to migrate to Rust. This venture required changing the tech stack, the libraries, the algorithms, implementing an LSM-like mechanism for the vector database, and so on. In other words, it was not a mechanical port but a migration with substantial rework.
