Delta CC-07 — Claude Code dossier

DELTA CC-07 / Claude Code

MCP bridge silently coerces array, object, number, and boolean tool parameters to strings — breaks strict-Zod connectors with no error signal

openopened ≤2026-05

Description

UPDATE 2026-07-04: #32524 — the canonical coercion issue, 9 duplicates, 'has repro' — was closed by stale-bot as not-planned (2026-07-03), NOT fixed. Per D0086, a stale closure never closes a delta; criterion (native-typed params + strict-Zod round-trip) not re-verified and not TD-executed this pass. Delta stays open.

Closes when

Non-string parameters arrive at MCP tools with native JSON types and a strict-Zod connector round-trip passes, re-verified

Evidence

[1][2]Re-verified 2026-07-04 (v2.1.201): #32524 closed stale/not-planned 2026-07-03 without a fix; no coercion fix in the v2.1.196–201 changelog
