fix: cap mcp below 2.0 — 2.0.0 removes Tool.inputSchema - #40
Merged
Conversation
mcp 2.0.0 (released after the last green main CI on 2026-07-08) breaks the tool-schema tests: Tool no longer exposes inputSchema. CI installs latest and fails on all six matrix legs; the lock is at 1.28.0. Cap at <2 until the code is migrated to the 2.x API.
