headlesson_search
shallowcom.headlesson/catalog · Verify this server
Find command-line tools, MCP servers and APIs for a task, and compare them. Ask in plain English or Japanese ("extract text from scanned PDFs") or by product name. Each result gives an ID, a one-line reason it matches, and when it was checked. Pass the ID to headlesson_get with sections ["lesson","gotchas"] to get the steps (install, check, first task) with their recorded test result (most were run by an agent; a few are untested) and known failure conditions, such as a tool that exits 0 with empty or wrong output. Filter or compare with axes such as auth, pricing, license and remote_mcp (where, axes, ids). Curated records come first. If none match, or include:["registry"] is set, one public word from the query is looked up in the Official MCP Registry; those listings are unverified (what is sent is described on the query field).
