discover_traits and synthesize_samples block-and-poll for up to 5 minutes and stream progress notifications on the same request — they do NOT return once enqueued. Only train is fire-and-forget. Updated: - tool table rows to say "Blocks until the run completes, streaming progress" for discover_traits and synthesize_samples vs "Enqueues the run and returns immediately" for train - explanatory prose below the table to distinguish the two behaviors and note that poll/get_model is only needed on timeout/disconnect for the blocking tools Evidence: api/mcp.py discover_traits (lines 1413-1500) and synthesize_samples (1510-1600) block-and-poll up to 300s; train returns after enqueue. https://claude.ai/code/session_015z6Nsyx37deuN4o7kAEQWZ

api-reference/mcp.mdx— MCP lifecycle tool async-behavior description was incorrect.The page stated that
train,discover_traits, andsynthesize_samplesall "return once the run is enqueued" and instructed callers to "pollget_modelfor the state rather than waiting on the call."Actual behavior (from
api/mcp.py):train— fire-and-forget: enqueues the run and returns immediately. Pollget_modelfor completion. ✓ (doc was correct for this one)discover_traits— blocks until the run finishes, streamingnotifications/progresson the same MCP request stream. May take several minutes.synthesize_samples— same blocking behavior asdiscover_traits.For
discover_traitsandsynthesize_samples, telling callers to "poll rather than waiting on the call" is actively wrong — the call already awaits completion.Fix
Updated the tool-table rows to distinguish the behaviors and rewrote the explanatory prose below the table. No other pages affected (the
/v1REST equivalents correctly say "202 Accepted" / async; MCP's blocking behavior is an MCP-layer concern documented only on this page).https://claude.ai/code/session_015z6Nsyx37deuN4o7kAEQWZ
