Setup Serena Mcp

This walks you through installing and configuring Serena MCP, a semantic code analysis server that gives Claude symbol-level understanding of your codebase. Instead of grepping through files, you get tools like find_symbol and find_referencing_symbols that work with your code's actual structure. The setup process handles three configuration scopes (project shared, project local, or global), checks prerequisites like uv, configures your MCP client, and updates your CLAUDE.md with usage guidelines. The real value is moving from text-based search to semantic navigation, which matters more as codebases grow. Worth the setup friction if you're doing serious refactoring or need precise cross-reference tracking.
