ephemora-cell 1.0.4: a stateless MCP tool server, now on PyPI!! A developer released ephemora-cell 1.0.4 on PyPI, a stateless MCP tool server that eliminates the initialize handshake and session state, allowing servers to be restarted or load-balanced between calls without clients noticing. The release adds CacheableResult fields (ttlMs: 3600000, cacheScope: "private") to tools/list responses and rejects unknown protocol versions with error -32022, while remaining compatible with handshake-era clients such as Claude Desktop, VS Code, and Codex. The author reports 13/13 acceptance checks against the published wheel and observed identical fuel consumption (21143) for the same echo call across two installs on different machines. No initialize handshake. No session state. Restart or load-balance the server between calls — clients never notice. tools/list answers with CacheableResult fields ttlMs: 3600000, cacheScope: "private" so hosts can cache the tool list, and unknown versions are rejected with -32022 naming the supported list — never silently swallowed. Handshake-era clients Claude Desktop, VS Code, Codex keep working unchanged. Both eras, one process — with a test that runs them mixed against one server instance. python reported = engine.policy for spec what get-policy says outcome = engine.execute spec, params what actually ran assert reported "preopens" == \ outcome.report.security baseline "preopens" How we verified it Fresh venv, plain pip install ephemora-cell, 13/13 acceptance checks against the published wheel: both MCP eras, version negotiation, policy/witness agreement, legacy compatibility unchanged. Bonus finding: the same echo call consumed identical fuel 21143 across two different installs on different machines — the determinism claim held in the wild.
