Been using Claude Code daily for a few months now and the thing that made the biggest difference wasn’t switching from Sonnet to Opus or tweaking my CLAUDE.md — it was building custom MCP servers. Once I connected Claude Code to our internal tools (JIRA, deployment pipeline, monitoring dashboards) through MCP, the productivity jump was insane. Instead of copy-pasting context from 5 different browser tabs, Claude just pulls what it needs directly. A few examples: - MCP server that reads our JIRA tickets and understands the full context of a task before I even explain it - One that queries our staging environment logs so Claude can debug production issues with real data - A simple one that manages git workflows with our team’s conventions baked in The model is smart, but the model + direct access to your actual tools is a completely different experience. If you’re still just using Claude Code with the default tools, you’re leaving a lot on the table. Anyone else building custom MCP servers? What integrations made the biggest difference for you? submitted by /u/ruibranco
