Code Lens vs Repomix
A side-by-side look at the Code Lens and Repomix MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Code Lens for developer tools work as a local process; choose Repomix for developer tools as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Code Lens when
- You need dedicated capabilities in the Developer Tools domain.
- You prefer a local stdio subprocess transport.
- You have the keys it needs:
GEMINI_API_KEY, GOOGLE_API_KEY. - You want tools like
generate_diff, analyze_pr_impact, generate_review_summary.
Choose Repomix when
- You need dedicated capabilities in the Developer Tools domain.
- You prefer a local stdio subprocess transport.
- You want tools like
pack_codebase, directory, compress.

Reduces token usage by ~70% while preserving semantic meaning. Generally not needed since grep_repomix_output allows incremental content retrieval. Use…includePatterns(Optional) Specify files to include using fast-glob patterns. Multiple patterns can be comma-separated (e.g., "**/*.{js,ts}", "src/**,docs/**"). Only matching files will be processed.ignorePatterns(Optional) Specify additional files to exclude using fast-glob patterns. Multiple patterns can be comma-separated (e.g., "test/**,*.spec.js", "node_modules/**,dist/**"). These patterns supplement .gitignore, .ignore, and built-in exclusions.outputPatterns(Optional) Per-file inclusion levels, mirroring the config-file `output.patterns` option.
