# Point Topic MCP Server Troubleshooting Report

## Issue Summary
MCP server working locally but environment variables not being passed to Claude Desktop deployment, causing missing tools and functionality.

## Timeline of Issues & Solutions

### Initial Problem: Import Errors with Snowflake
- **Issue**: Server failed with "No module named 'snowflake'" when importing snowflake.connector
- **Root Cause**: Snowflake dependency not included in MCP deployment
- **Solution**: Used `--with "snowflake-connector-python[pandas]"` flag during installation
- **Command**: `uv run mcp install server.py --with "snowflake-connector-python[pandas]"`

### File Structure Changes
- **Issue**: Relative import problems with nested directory structure
- **Solution**: Moved files to top level temporarily to isolate import issues
- **Current Structure**: Proper src/point_topic_mcp/ structure maintained in pyproject.toml

### Environment Variables Not Passed to Production
- **Issue**: MCP server deployed without environment variables, causing:
  - Only basic tools available (server info tools)
  - Missing ADMIN_API_KEY meant admin tools not enabled
  - Missing database credentials meant Snowflake tools unavailable
  - Missing API keys meant GitHub/Chart tools unavailable

- **Root Cause**: Claude Desktop configuration missing environment variables
- **Solution**: Reinstalled MCP server with `-f .env` flag to include all environment variables
- **Command**: `uv run mcp install src/point_topic_mcp/server_local.py --name "Point Topic MCP" -f .env`

### Dependencies in pyproject.toml
- **Status**: ✅ All dependencies properly declared in pyproject.toml
- **Dependencies**: 
  - snowflake-connector-python>=3.17.3 ✅
  - All other required packages ✅

## Final Working Configuration

### Claude Desktop Config Location
`/Users/peterdonaghey/Library/Application Support/Claude/claude_desktop_config.json`

### Environment Variables Now Included
- ✅ ADMIN_API_KEY (enables all admin tools)
- ✅ SNOWFLAKE_USER & SNOWFLAKE_PASSWORD (enables database tools) 
- ✅ GITHUB_TOKEN (enables GitHub tools)
- ✅ CHART_API_KEY (enables chart generation tools)
- ✅ All other environment variables from .env file

### Key Lessons Learned
1. **MCP deployment doesn't automatically read .env files** - must explicitly pass with `-f .env`
2. **Environment variables are critical for conditional tool availability**
3. **ADMIN_API_KEY presence determines whether all tools are available**
4. **pyproject.toml dependencies work correctly** - the `--with` flags are for additional runtime dependencies not declared in the project
5. **Always restart Claude Desktop after configuration changes**

## Current Status: ✅ RESOLVED
- Server properly configured with all environment variables
- All tools should now be available when ADMIN_API_KEY is present
- Dependencies properly managed through pyproject.toml
- Clean Claude Desktop configuration without duplicates

## Next Steps
1. Restart Claude Desktop to pick up new configuration
2. Verify all tools are available in Claude
3. Test database connectivity with Snowflake tools
