Set up CellTypist as a remote tool

Validation status (2026-08-16): working CPU deployment. The live MCP call annotated 80 cells from the official CellTypist sample and completed majority voting. A converted data-only model produced the same 80 labels and probabilities as the digest-pinned upstream model (maximum probability delta 0.0). This is runtime equivalence evidence, not an annotation-accuracy benchmark. 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 is sufficient for the validated model and sample.
• 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.
