I built a basic MCP server for `flyctl` that took only 30 minutes, exposing just two commands: `fly logs` and `fly status`. The MCP server is useful because it can discover tools exported by the server, such as running arbitrary Python code with a tool call. This allows an LLM to use the MCP server to scrape the web or perform other tasks. The MCP server was tested on an unpkg application, which reported stability issues and memory-related crashes in some machines. The MCP server was able to identify the root cause of these issues and provide detailed logs and health checks, allowing for faster problem-solving. However, the author is cautious about running local MCP servers due to concerns about giving a cloud instance native program access on their machine. Overall, the MCP server is surprisingly useful and fast, but its use requires careful consideration.
