MCP Server API Helpers Lacked Error Handling, Causing Crashes

By PulseAugur Editorial · [1 sources] ·

The author discovered that two critical API helper functions in their MCP server, used for interacting with GitHub and DEV.to, lacked any error handling. Unlike other functions that had been progressively hardened, these two would crash the server with raw Python tracebacks when encountering common issues like invalid IDs or expired tokens. The author contrasts this with a more robust error handling pattern already implemented for a Claude API wrapper, which returns a clean error message instead of an unhandled exception. AI

    My MCP Server's Two API Helpers Had Zero except Blocks. Every Bad Call Crashed With a Raw urllib Traceback.

    <p>I've spent the last few weeks hardening one function in my MCP server's <code>claude -p</code> wrapper. First a timeout fix. Then it turned out the timeout fix didn't cover a non-zero exit code. Then it turned out <em>that</em> fix still didn't cover a missing binary. Three se…
