btx-fix-mcp 2.0.1

MCP servers for code review and automated fixing

btx_fix_mcp

Code review and automated fixing tools - available as CLI and MCP server.

What is btx_fix_mcp?

btx_fix_mcp provides comprehensive code analysis:

• 18+ Quality Analyses: Complexity, maintainability, duplication, type coverage, dead code
• Security Scanning: Bandit integration for vulnerability detection
• Cache Optimization: Evidence-based @lru_cache recommendations
• Documentation Coverage: Docstring completeness analysis

Two ways to use it:

Mode	Best For
CLI	Direct command-line usage, CI/CD pipelines, scripts
MCP Server	Integration with Claude Desktop, AI-assisted workflows

---

Quick Start

Installation

# Recommended: uv
pip install uv
uv pip install btx_fix_mcp

# Alternative: pip
pip install btx_fix_mcp

# Development
git clone https://github.com/bitranox/btx_fix_mcp
cd btx_fix_mcp && make dev

CLI Usage (Simple)

# Deploy configuration (recommended first step) - this creates a config file with the settings for all tests to adjust
btx_fix_mcp config-deploy --target app

# Review uncommitted git changes (default)
btx_fix_mcp review all

# Review all files
btx_fix_mcp review all --mode full

# Run specific analysis
btx_fix_mcp review quality
btx_fix_mcp review security

# Cache optimization with profiling (recommended)
btx_fix_mcp review profile -- python -m your_app    # Profile your app
btx_fix_mcp review profile -- pytest tests/         # Or profile tests
btx_fix_mcp review cache                            # Then analyze

# Clean up analysis data
btx_fix_mcp review clean                            # Delete all
btx_fix_mcp review clean -s profile                 # Delete profile only
btx_fix_mcp review clean --dry-run                  # Preview deletion

MCP Server Usage (Simple)

Add to Claude Desktop config (~/.config/claude/claude_desktop_config.json):

{
  "mcpServers": {
    "btx-review": {
      "command": "python",
      "args": ["-m", "btx_fix_mcp.servers.review"]
    }
  }
}

Then in Claude Desktop:

"Review the code quality of this project"

Requirements

• Python 3.13+
• Git (optional)

Git Integration

Git is optional but enables additional features:

Feature	Without Git	With Git
Scope Mode	--mode full scans all files	--mode git scans only uncommitted changes (default)
Code Churn	Skipped	Analyzes frequently modified files
Branch Info	Shows "N/A"	Displays current branch

When git is not available:

• --mode git automatically falls back to --mode full with a warning
• Code churn analysis is skipped silently
• Cache analysis works without git (uses in-memory file backup)
• All other analyses work normally
