Code Intelligence MCP Server 🧠

Give your AI agents a "brain" that actually understands your codebase. This Model Context Protocol (MCP) server provides high-performance semantic search and deep code insights, making it easier for AI tools to navigate, understand, and modify complex projects.

This is not just a search tool; it is an analysis engine. While standard Indexers just treat files as pure text, code-intel parses your codebase into a living knowledge graph. It maps abstract syntax trees (ASTs), dynamic dependencies, and architectural patterns, allowing your AI to enforce strict methodologies, understand blast radiuses, and confidently pair-program on enterprise-grade software.

🚀 Quick Start

1. Prerequisites

Install Ollama and pull the high-precision embedding model:

ollama pull unclemusclez/jina-embeddings-v2-base-code

2. Installation

Choose one of the following methods to set up the project:

Option A: Clone the Repository (Recommended)

Best for active development and staying up to date.

git clone https://github.com/nairraf/code-intel.git
cd code-intel
uv sync

Option B: Download Release (Quick Start)

Best for a one-time setup or if you don't have Git installed.

1. Download the latest Source ZIP or Tarball.
2. Extract the archive to your desired location.
3. Open a terminal in the folder and run:

   uv sync
   

3. MCP Configuration

Add the following to your AI client's MCP settings (e.g., Claude Desktop, Cursor, or Antigravity mcp_config.json). Replace /path/to/code-intel with the absolute path to this project.

{
  "mcpServers": {
    "code-intel": {
      "command": "uv",
      "args": ["run", "--quiet", "--directory", "/path/to/code-intel", "python", "-m", "src.server"],
      "env": { "PYTHONUNBUFFERED": "1" }
    }
  }
}

🎯 Unique Advantages for Structured Engineering

While many tools offer basic semantic search, code-intel is purpose-built to enforce strict architectural rules and support advanced software engineering methodologies:

• Project Pulse & Health Metrics: Go beyond simple search. The internal engine actively identifies "Dependency Hubs" and "High-Risk Symbols" (files with high complexity but low test coverage), guiding refactoring efforts and enforcing test-gated workflows.
• Deep Framework Analysis: Standard indexers often fail at mapping dynamic patterns. This server specifically tracks dynamic dependency injection (like Python's Depends()) and framework-specific middleware, allowing developers to keep business logic pure and fully mockable.
• Targeted Re-Indexing: Working in a massive mono-repo? You don't need to re-index the entire universe. Use targeted include/exclude patterns to update the knowledge graph on-the-fly for only the microservice or module you are actively developing.
• Contract-First Validation: By exposing the precise call graph and interface definitions, code-intel helps validate that implementations adhere to established API contracts and structural patterns before code is committed.

✨ Key Features

Intelligent Caching

Our embedding cache drastically reduces latency. By storing "fingerprints" of your code locally, we avoid re-calculating embeddings for unchanged files, making searches nearly instantaneous.

Semantic "Meaning-Based" Search

Go beyond simple keyword matching. Search for concepts like "how do we handle user authentication?" and find the relevant logic even if the exact words aren't used.

Cross-File Architecture Graph

A persistent knowledge graph tracks imports and function calls across your entire project. This enables precise "Jump to Definition" and "Find References" that work reliably across many files, including advanced structural tracking for Dart widget instantiations and Python dependency injection (Depends()).

Security & Quality Hardened

Independently audited and remediated against OWASP Top 10 vulnerabilities. Includes robust sanitization for vector filters, safe JSON-based serialization, and strict path containment.

🛠️ Tools & Tools Usage

Tool	Benefit to Cloud AI
search_code	Token Saver: Feeds the AI only the specific logic it needs to solve a task.
get_stats	Strategic Overview: Identifies "Dependency Hubs" and "High-Risk" areas.
find_definition	Precise Navigation: Jumps straight to the source of any symbol.
find_references	Impact Analysis: Helps the AI understand side-effects across files.
refresh_index	On-Demand Sync: Manually triggers a scan to update the code map.

💡 Example AI Prompts

Try asking your AI agent:

• "Give me a high-level overview of the dependency hubs in this project and identify any potential technical debt."
• "Find where the AuthenticationService is defined and show me all the places it is referenced."
• "How does this project handle error logging across different modules?"

🌐 Supported Languages

While we support 80+ languages via Tree-sitter, we provide optimized resolution for:

• Python (Advanced import resolution, FastAPI/Flask dependency injection)
• Dart / Flutter (Package resolution, Widget structural mapping)
• TypeScript / JavaScript (ESM/CommonJS module resolution)
• Go & Rust

🔧 Troubleshooting

Issue	Potential Solution
"Connection Refused"	Ensure Ollama is running (ollama serve).
"Model Not Found"	Run ollama pull for the Jina model.
"0 Chunks Indexed"	Ensure project root path is absolute and extensions are supported.
Slow Performance	First-time indexing is resource-intensive; subsequent runs use the cache.
