Set up Scrublet as a remote tool

Validation status (2026-08-16): installation, direct/live MCP calls, traversal rejection, and prior same-host concurrency levels 1, 2, and 4 passed. Two current 500-cell calls returned finite aligned results and 429 synthetic predictions; that 85.8% fixture rate is not an accuracy result. Public publication, cross-user isolation, representative accuracy, cancellation, and recovery remain incomplete. Authenticated private Platform import and owner testing passed on 2026-08-16; public publication and independent-caller authorization/isolation remain untested.

Prerequisites

• Run from the ToolUniverse repository root on Linux with Python 3.12.3.
• CPU only; size RAM for count matrices.
• Keep provider data, weights, caches, and credentials outside Git.
• Bind to loopback. A non-loopback bind requires TOOLUNIVERSE_API_TOKEN; never put it in arguments or results.
