### SUMMARY Add `MCP_PARSE_REQUEST_ENABLED` config option (default: `True`) to control whether the `parse_request` decorator applies its string-to-model parsing workaround for MCP tools. The `parse_request` decorator was introduced to work around a [Claude Code double-serialization bug](https://github.com/anthropics/claude-code/issues/5504) where requests arrive as JSON strings instead of objects. When set to `False`, the decorator becomes a no-op and returns the original function unchanged, letting FastMCP handle request parsing natively. **Changes:** - Add `MCP_PARSE_REQUEST_ENABLED = True` default in `mcp_config.py` - Add `_is_parse_request_enabled()` helper that checks Flask config (with fallback chain) - Early return in `parse_request` decorator when disabled ### BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF N/A - no UI changes ### TESTING INSTRUCTIONS 1. Default behavior (enabled): Verify MCP tools continue to accept both JSON string and object requests as before 2. Disabled: Set `MCP_PARSE_REQUEST_ENABLED = False` in `superset_config.py`, verify MCP tools work with FastMCP's native request parsing (object-only, no string workaround) ### ADDITIONAL INFORMATION - [ ] Has associated issue: - [ ] Required feature flags: - [ ] Changes UI - [ ] Includes DB Migration - [x] Introduces new feature or API - [ ] Removes existing feature or API -- This is an automated message from the Apache Git Service.
