Developer prioritizes model reliability over token savings for boat agent MCP server

By PulseAugur Editorial · [1 sources] ·

A developer evaluated two approaches for a SignalK MCP server: a single `execute_code` tool versus discrete named tools. While the `execute_code` approach, used by VesselSense/signalk-mcp-server, offers significant token savings (90-96%) by allowing models to write and execute JavaScript, it requires high model reliability. The author found that smaller, local models struggle with generating correct code, making reliability the primary concern over token efficiency. Consequently, they opted to maintain their existing discrete named-tool server, incorporating ideas from the VesselSense design. AI

    Why we kept named MCP tools despite a 96% token saving

    <p>The boat-agent stack here runs on a prime directive: if there's something usable out there, improve it; build our own only as a last resort. So when we needed a SignalK MCP server, the honest first move wasn't to write one — it was to evaluate the one that already exists.</p> …
