What coding agents actually see when searching MCP tools — and why discoverability is bad
_babush_ · reddit · 2026-10-30
The author benchmarked how coding agents search MCP tools using their company's reverse-engineering MCP server as a case study, finding discoverability results disappointing. The post surveys how different harnesses and coding CLIs handle tool search, what MCP developers can do about it, and experiments tracking progress. General and useful for anyone writing MCP servers.
