New Business-Relevant Servers¶

Notes¶
- mcpservers.org /all page 1: all 15 non-sponsor entries already evaluated in prior sweeps (top five were the Sep 6 midday candidates AdPlug/Encited/Bynn/Voibe/earn-*; WakeMark, ShopSynch, CareClinic, fetcher.sh family, Global Travel, UK Premises, Solana Snipe, AskPod all carry prior skip dispositions).
- GitHub net since the night sweep cutoff: 455 created, sampled top 15 - all zero-star hobby/spam repos (playwright clones, no-description MCP wrappers), none passing the business-operator filter.
- mcp.so feed carried exactly two blocks newer than the night sweep (PostNitro 16:29Z, Yocoolab 12:44Z); everything else was prior-sweep territory (TrueClicks and studiofromthesea were the night sweep's own dispositions).
