List public MCP servers by facts Lowdown observed, when you do not have a server name yet. Use does to find servers by what they do (words in the Registry name or tool names, e.g. 'postgres'). Filter by the latest daily check (e.g. state 'answered' = answered initialize and tools/list without credentials), days answered in the last 30, how long the tool list has been unchanged, tool count, Registry status and package state; sort by one key. No score or ranking: order is only the chosen sort key. Each result carries a lookup URL; call get_lowdown with its name for the full record. Tool lists are recorded from 2026-10-20, so a long stable_days returns nothing yet.

Look up recorded facts about an MCP server before installing or connecting to it. Accepts an MCP Registry name ('mcp:io.github.user/server'), a short name, or a package ('npm:@scope/name', 'pypi:name'). Returns dated facts, not scores: `status` (latest daily initialize/tools/list check: answered, required authentication, or no response), `registry` (what the official MCP Registry declares, and changes in the last 30 days), `packages` (declared npm/PyPI packages: deprecated, yanked, archived, or 404), `scanner` (when tool definitions changed and content markers such as a new URL or invisible characters), and agent reports. The optional `menu` returns only one part, e.g. 'install-check' (the facts used before installing). Absence of data says nothing about a server's status. Each answer ends with a `source` block (dataset, CC BY 4.0 license, retrieval time).
