How I Automated AI-Generated Commit Messages in Cursor IDE and Saved Hours

June 19, 2025
As an AI developer working daily in Cursor IDE, I couldn’t wait to use MCP servers to supercharge my coding. But honestly? The setup felt like wrestling with a tangled headset cable. Installation headaches, prompt overloads, and constant server juggling almost made me quit. Here’s how I fought back and won.
The Speed Bumps That Drove Me Crazy
When I first tried MCP servers in Cursor, these five issues kept tripping me up:
- Adding servers one-by-one through that tiny popup window felt like data entry punishment. No copy-paste? Seriously?
- Needing to fully delete and re-add servers I only used occasionally wasted so much coffee time.
- Tool descriptions gobbled over 17,000 tokens per prompt – my AI responses crawled like rush hour traffic.
- Windows installations failed without error messages. At least MacOS told me why it was mad!
- No config file support meant rebuilding my Claude Desktop setups from memory every single time.
How I Fixed My MCP Workflow
After weeks of experiments and late nights, here’s what actually worked:
- For API keys, I used this command format:
env KEY_NAME=<VAR> <MCP Command>. Likeenv GITHUB_PERSONAL_ACCESS_TOKEN=my_token npx -y @modelcontextprotocol/server-github– keeps secrets safe. - I built custom JSON configs to manage multiple servers at once. This snippet became my best friend:
{
"mcpServers": {
"Jupyter-notebook-manager": {
"command": "uv",
"args": ["run", "--with", "mcp-server-jupyter", "mcp-server-jupyter"],
"env": {
"UV_PROJECT_ENVIRONMENT": "/path/to/venv"
}
}
}
} - For token dieting, I stored only tool names in configs, loading full descriptions only when needed. My prompts lost 80% of their bloat!
- On Windows, Git Bash plus permission fixes finally stopped those silent failures.
- Grouping tools into categories like “debugging” or “file ops” made my AI assistant smarter about picking the right tool.
Practical Wins For Your Setup
These changes didn’t just help – they transformed my workflow:
- Config files are lifesavers. Bug Cursor’s team to add proper import/export!
- Semantic grouping slashes token costs. Only load what you need for each task type.
- Keep a “graveyard” JSON for broken servers – you might fix them later when inspiration strikes.
- We all deserve enable/disable toggles and clear error messages. Keep requesting these!
With these tweaks, MCP servers went from frustrating to fantastic. Now I spend less time configuring and more time creating. And isn’t that why we use these tools in the first place?
