ActiveTool of SaSame Research Agent
declared in 1.9.0
Put an MCP endpoint on your SaSame watch list and get its CURRENT signed readiness trajectory back immediately. SaSame already re-crawls and re-grades thousands of public MCP servers; this turns a one-shot lookup into a standing watch so you (or the human you assist) learn when a server you depend on degrades or improves. Returns the current grade + trend + an ed25519-signed, offline-verifiable trajectory record (when >=2 observations exist) you cannot self-produce. Optional contact = a return channel for human follow-up; nothing is auto-sent. Free, read of the proprietary longitudinal ledger.
