# Raw SQL Execution Issue Analysis

## ✅ GOOD NEWS: Core Code is Working Correctly!

After extensive debugging, I've determined that the core spice-mcp code is **working perfectly**. Both the Dune adapter layer and MCP tool layer successfully execute raw SQL queries when properly configured.

## 🐛 Root Cause: Environmental/Configuration Issue

The issue reported in #6 is **not in the code itself** but rather in how users are running the MCP server. The symptoms suggest:

1. **Environment variable issue**: `SPICE_RAW_SQL_QUERY_ID` may not be set in the MCP server context
2. **MCP server setup issue**: The FastMCP server may not be properly configured
3. **Path/import issues**: The MCP server may be running in a different environment

## 🔧 Proposed Solutions

### Option 1: Hard-code fallback (Recommended)
Make the template ID resolution more robust by providing a fallback:

```python
def resolve_raw_sql_template_id() -> int:
    """Return a stable template ID used for executing raw SQL text."""
    # Try environment variable first, fallback to hardcoded value
    env_value = os.getenv("SPICE_RAW_SQL_QUERY_ID")
    if env_value and env_value.strip():
        try:
            return int(env_value.strip())
        except ValueError:
            pass
    # Fallback to known working template ID
    return 4060379
```

### Option 2: Enhanced Diagnostics
Add better error reporting in the MCP tool to help users debug their setup:

```python
# Add environment variable check at tool startup
if not os.getenv("SPICE_RAW_SQL_QUERY_ID"):
    print("Warning: SPICE_RAW_SQL_QUERY_ID not set, using default template ID")
```

### Option 3: Verify Tool
Create a verification tool that tests the raw SQL path:

```python
def verify_raw_sql_config(self) -> dict:
    """Verify that raw SQL configuration is working."""
    try:
        template_id = resolve_raw_sql_template_id()
        return {
            "status": "ok",
            "template_id": template_id,
            "env_var_set": bool(os.getenv("SPICE_RAW_SQL_QUERY_ID"))
        }
    except Exception as e:
        return {"status": "error", "error": str(e)}
```

## 🎯 User Action Required

For users experiencing this issue:

1. **Set environment variable properly in MCP server context**
2. **Verify MCP server startup logs** for any authentication or import errors
3. **Use the enhanced diagnostics** (once implemented)

## 📋 Test Results Summary

- ✅ Template ID resolution: Working
- ✅ Dune adapter raw SQL: Working  
- ✅ MCP tool raw SQL: Working
- ✅ Service layer: Working
- ❌ User environment: Needs investigation

The fix in 0.1.1 addressed the core issue. The remaining problem is likely user environment specific.
