**Lines**: 30, 32, 34, 36
```
2025-10-07T13:23:31.803Z [WordPress MCP Server] [info] Message from server: {"jsonrpc":"2.0","id":4,"error":{"code":-32603,"message":"keyValidator._parse is not a function"}}

**Affected Tools**:
- `wp_test_auth` (line 30)
- `wp_get_auth_status` (line 32)
- `wp_get_site_settings` (line 34)
- `wp_list_posts` (line 36)
**Impact**: **ALL TOOLS FAIL** - No WordPress operations work

## Non-Critical Issues
### 1. Method Not Found - prompts/list
**Lines**: 12, 27, 54
```
Message from server: {"jsonrpc":"2.0","id":2,"error":{"code":-32601,"message":"Method not found"}}
```
**Cause**: Client requests `prompts/list` but server doesn't implement it
**Impact**: Prompts not available (but this is expected - server doesn't expose prompts endpoint)
**Status**: Expected behavior, not a bug
### 2. Method Not Found - resources/list
**Lines**: 13, 28, 55
```
Message from server: {"jsonrpc":"2.0","id":3,"error":{"code":-32601,"message":"Method not found"}}
```
**Cause**: Client requests `resources/list` but server doesn't implement it
**Impact**: Resources not available (but this is expected - server doesn't expose resources endpoint)
**Status**: Expected behavior, not a bug

## Root Cause Analysis
### Problem: Zod Schema Validation Error
The error `keyValidator._parse is not a function` indicates a **Zod validation library issue**.
### Location
This error happens during tool execution, likely in the tool wrapper or validation layer.
### Possible Causes
1. **Zod Version Mismatch**
- DXT bundled dependencies might have wrong Zod version
- Production dependencies might be incompatible
2. **Schema Definition Error**
- Invalid schema structure in tool definitions
- Missing or incorrect validator configuration
3. **DXT Compilation Issue**
- TypeScript compilation produced invalid code
- Module resolution failing for Zod imports
---
## Investigation Needed
### Files to Check
1. **Tool Validation Layer**
- `src/utils/validation.ts`
- `src/server/ToolRegistry.ts`
- `src/tools/BaseToolManager.ts`
2. **Zod Schema Usage**
- `src/config/ConfigurationSchema.ts`
- Any files using Zod `.parse()` or validators
3. **Package Dependencies**
- `package.json` - Zod version
- `package-lock.json` - Actual installed version
- DXT `node_modules/` - What's actually bundled

## Server Info from Log
**Version Reported**: `2.7.0` (line 6, 21, 48)
**Expected Version**: `2.10.2`
This confirms the **old DXT package was being used** during the logged session.
---
## Next Steps
1. ✅ Find Zod usage in validation code
2. ✅ Check for schema definition issues
3. ✅ Verify Zod version in dependencies
4. ✅ Test with corrected DXT package (v2.10.2)
5. ⏳ Rebuild and reinstall DXT
