+Fix MCP server compatibility with Draft-07 clients (Augment IDE, gemini-cli, gemini code assist)
+
+- Resolves #1284
+
+**Problem:**
+
+- MCP tools were using Zod v4, which outputs JSON Schema Draft 2020-12
+- MCP clients only support Draft-07
+- Tools were not discoverable in gemini-cli and other clients
+
+**Solution:**
+
+- Updated all MCP tools to import from `zod/v3` instead of `zod`
+- Zod v3 schemas convert to Draft-07 via FastMCP's zod-to-json-schema
+- Fixed logger to use stderr instead of stdout (MCP protocol requirement)
+
+This is a temporary workaround until FastMCP adds JSON Schema version configuration.
