Gemini-powered MCP server for automated code review, analysis, and documentation. ## Overview Code Lens is a [Model Context Protocol](https://modelcontextprotocol.io/) server that uses Google Gemini to analyze diffs, review pull requests, detect code smells, generate documentation, and verify logic. It exposes 13 tools, 7 resources, and 5 prompts over stdio transport. ## Key Features - **PR review pipeline** — generate diffs, assess impact, detect breaking API changes, and produce review summaries with merge recommendations - **File analysis** — load any source file for refactoring suggestions, code smell detection, documentation generation, and natural-language Q&A - **Logic verification** — verify algorithms using Gemini's code execution sandbox - **Structured outputs** — all tools return validated JSON via Zod v4 output schemas - **Web search** — Google Search with Grounding for up-to-date information retrieval - **Task lifecycle support** — every tool except `load_file` can run via MCP tasks with polling, cancellation, and progress updates ## Requirements - Node.js >= 24 - A [Gemini API key](https://aistudio.google.com/apikey) (`GEMINI_API_KEY` or `GOOGLE_API_KEY`) ## Quick Start ```json { "mcpServers": { "code-lens": { "command": "npx", "args": ["-y", "@j0hanz/code-lens-mcp@latest"], "env": { "GEMINI_API_KEY": "your-api-key" } } } } ``` ### Docker ```bash docker run -i --rm -e GEMINI_API_KEY="your-api-key" ghcr.io/j0hanz/code-lens ``` Or with Docker Compose: ```bash GEMINI_API_KEY=your-api-key docker compose up ``` ## Client Configuration

## Use Cases ### PR Review Pipeline 1. Call `generate_diff` to capture unstaged or staged changes 2. Run `analyze_pr_impact` to assess severity and breaking changes 3. Run `generate_review_summary` for a risk rating and merge recommendation 4. Run `detect_api_breaking_changes` to check for public API breakage 5. Run `generate_test_plan` to produce prioritized test cases ### Single-File Analysis 1. Call `load_file` to cache a source file 2. Run `refactor_code` for structural improvement suggestions 3. Run `detect_code_smells` for Fowler-taxonomy anti-patterns 4. Run `generate_documentation` to generate JSDoc/TSDoc stubs 5. Use `ask_about_code` for natural-language Q&A about the file 6. Use `verify_logic` to verify algorithms with code execution ### Performance Audit 1. Call `generate_diff` on a performance-sensitive change 2. Run `analyze_time_space_complexity` to detect Big-O degradation ### Research - Use `web_search` for up-to-date documentation or API references via Google Search with Grounding ## Architecture ```text [MCP Client] │ │ Transport: stdio ▼ [MCP Server: code-lens] │ Entry: src/index.ts → src/server.ts │ ├── initialize / initialized (lifecycle handshake) │ ├── tools/call ────────────────────────────────────────────── │ │ │ │ Diff-based tools (require generate_diff first): │ ├── [generate_diff] Sync — capture git diff │ ├── [analyze_pr_impact] Flash — severity & impact │ ├── [generate_review_summary] Flash — risk & merge rec │ ├── [generate_test_plan] Flash — test cases │ ├── [analyze_time_space_complexity] Flash — Big-O analysis │ ├── [detect_api_breaking_changes] Flash — API breakage │ │ │ │ File-based tools (require load_file first): │ ├── [load_file] Sync — cache source file │ ├── [refactor_code] Flash — refactoring │ ├── [detect_code_smells] Flash — smell detection │ ├── [generate_documentation] Flash — doc stubs │ ├── [ask_about_code] Flash — Q&A │ ├── [verify_logic] Flash — code execution │ │ │ │ Standalone: │ └── [web_search] Flash — Google Search │ ├── resources/read ────────────────────────────────────────── │ ├── [internal://instructions] Server usage guide │ ├── [internal://tool-catalog] Tool reference │ ├── [internal://workflows] Workflow sequences │ ├── [internal://server-config] Runtime config │ ├── [internal://tool-info/{name}] Per-tool details │ ├── [internal://diff/current] Cached diff (text/x-patch) │ └── [internal://file/current] Cached source file │ ├── prompts/get ───────────────────────────────────────────── │ ├── [get-help] Full server instructions │ ├── [review-guide] Tool + focus area workflow │ ├── [select-workflow] Pipeline by change type │ ├── [analyze-file] File analysis pipeline │ └── [tool-chain] Tool prerequisite chain │ └── Capabilities: structured output, tool annotations, notifications ``` ### Request Lifecycle ```text [Client] -- initialize {protocolVersion, capabilities} --> [Server] [Server] -- {protocolVersion, capabilities, serverInfo} --> [Client] [Client] -- notifications/initialized --> [Server] [Client] -- tools/call {name, arguments} --> [Server] [Server] -- notifications/progress {token, progress, total} --> [Client] [Server] -- {content, structuredContent, isError?} --> [Client] ``` ### Task Lifecycle - `generate_diff` and `load_file` are sync-only. All other tools advertise `taskSupport: optional`. - Requestors may supply a task TTL. The server uses that value up to `MAX_TASK_TTL_MS`, or falls back to `TASK_TTL_MS` when omitted. - Cancelled tasks remain terminal as `cancelled`, and `tasks/result` returns a cancellation-shaped tool result. ## MCP Surface ### Tools | Tool | Description | Prerequisite | Model | | ------------------------------- | ------------------------------------------------------------------ | --------------- | ----- | | `generate_diff` | Capture git diff (unstaged/staged) and cache server-side | — | Sync | | `analyze_pr_impact` | Assess severity, categories, breaking changes, rollback complexity | `generate_diff` | Flash | | `generate_review_summary` | PR summary, risk rating, merge recommendation | `generate_diff` | Flash | | `generate_test_plan` | Prioritized test cases and coverage guidance | `generate_diff` | Flash | | `analyze_time_space_complexity` | Big-O complexity analysis and degradation detection | `generate_diff` | Flash | | `detect_api_breaking_changes` | Detect breaking API/interface changes | `generate_diff` | Flash | | `load_file` | Cache a source file for analysis tools | — | Sync | | `refactor_code` | Complexity, duplication, naming, grouping suggestions | `load_file` | Flash | | `detect_code_smells` | Structural code smells (Fowler taxonomy) | `load_file` | Flash | | `generate_documentation` | JSDoc/TSDoc/docstring stubs for public exports | `load_file` | Flash | | `ask_about_code` | Natural-language Q&A about a cached file | `load_file` | Flash | | `verify_logic` | Verify algorithms via Gemini code execution sandbox | `load_file` | Flash | | `web_search` | Google Search with Grounding | — | Flash | ### Resources | URI | Description | MIME | | --------------------------------- | -------------------------------------------------- | --------------- | | `internal://instructions` | Complete server usage instructions | `text/markdown` | | `internal://tool-catalog` | Tool reference: models, params, outputs, data flow | `text/markdown` | | `internal://workflows` | Recommended workflows and tool sequences | `text/markdown` | | `internal://server-config` | Runtime configuration and limits | `text/markdown` | | `internal://tool-info/{toolName}` | Per-tool details (parameterized) | `text/markdown` | | `internal://diff/current` | Most recently generated diff | `text/x-patch` | | `internal://file/current` | Most recently loaded source file | `text/plain` | ### Prompts | Prompt | Description | | ----------------- | --------------------------------------------------------------------- | | `get-help` | Full server instructions: capabilities, tools, resources, constraints | | `review-guide` | Workflow guide for a specific tool and focus area | | `select-workflow` | Recommended tool pipeline based on change type | | `analyze-file` | Goal-based tool pipeline for single-file analysis | | `tool-chain` | Full prerequisite chain for a given tool | ## MCP Capabilities ### Tool Annotations All tools expose MCP tool annotations: | Annotation | Used | | ----------------- | ---- | | `readOnlyHint` | Yes | | `destructiveHint` | Yes | | `idempotentHint` | Yes | | `openWorldHint` | Yes | ### Structured Output All Gemini-powered tools return validated `structuredContent` alongside text `content`, using Zod v4 output schemas. ## Configuration | Variable | Default | Description | | ------------------------------ | ------------------------ | ----------------------------------------------------------------------------------------------------------- | | `GEMINI_API_KEY` | — | **Required.** Gemini API key.
