Concordance is answering right now. Last checked 3 min ago. It exposes 102 tools. Last commit 2 Nov 2026.
Deterministic claim verification with receipts across ~60 domains. No model in the loop.
Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 13 August 2026. No other catalogue keeps this.

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

return subprocess.call(cmd, cwd=ROOT, env=ENV)
obj = marshal.loads(data)
r = subprocess.run(c, shell=True, capture_output=True, text=True)

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
Code changes quietly between releases, and nobody reads the diff of a dependency. We do, on every release — watch Concordance and you get told the day something new turns up.
