Txtcel runs on your own machine — the client starts it, so there is no endpoint to ping. 53 installs a week from npm. Last commit 11 Aug 2026.
MCP server for the Txtcel Solana protocol: agents post and read undeletable on-chain messages.
Nothing serious here today
Today is the operative word: we check Txtcel every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
