The Problem

AI agents can write code, explain errors, and suggest commands — but they can't actually install software on your machine. When you say "help me set up ComfyUI", the AI gives you a wall of commands and hopes for the best.

gitinstall bridges this gap. It's an MCP server that gives any AI agent (Claude, Cursor, Copilot, etc.) the ability to:

1. Detect your system (OS, GPU, runtimes, package managers)
2. Plan the installation with intelligent multi-strategy planning
3. Execute safely with dangerous command blocking
4. Auto-fix errors (PEP 668, CUDA mismatch, missing tools, and more)
5. Retry with fallback strategies if the first approach fails

Quick Start

For Claude Desktop

pip install gitinstall

Add to ~/.claude/claude_desktop_config.json:

{
  "mcpServers": {
    "gitinstall": {
      "command": "gitinstall-mcp"
    }
  }
}

Restart Claude Desktop. Now you can say:

"Help me install ComfyUI on this machine"

Claude will call gitinstall's tools to detect your system, generate a plan, and execute it — with real-time progress updates and automatic error recovery.

For Cursor

Add to Cursor's MCP settings:

{
  "mcpServers": {
    "gitinstall": {
      "command": "gitinstall-mcp"
    }
  }
}

For VS Code (Copilot)

Add to your VS Code settings.json:

{
  "mcp": {
    "servers": {
      "gitinstall": {
        "command": "gitinstall-mcp"
      }
    }
  }
}

For any MCP client

gitinstall-mcp    # Starts MCP server on stdio (JSON-RPC 2.0)

MCP Tools

gitinstall exposes 6 tools via MCP:

Tool	What it does
install_github_project	End-to-end installation: detect → plan → execute → auto-fix → fallback retry
diagnose_install_error	Diagnose any build/install error and return fix commands
detect_environment	Report OS, CPU, GPU, runtimes, package managers, disk space
get_project_info	Fetch GitHub project metadata without installing
check_system_health	Full system diagnostic with fix suggestions
audit_dependencies	Scan project dependencies for known CVEs

Example: install_github_project

The AI calls:

{
  "name": "install_github_project",
  "arguments": {
    "project": "comfyanonymous/ComfyUI"
  }
}

gitinstall handles everything:

• Detects macOS Apple Silicon M3 + Python 3.12 + brew
• Generates 3-step plan (clone → install PyTorch MPS → install deps)
• Executes each step with safety checks
• If pip install fails with PEP 668, auto-fixes with python -m venv
• Returns success status + launch command

Example: diagnose_install_error

Pass any build error to the AI, and gitinstall will identify the root cause and return fix commands automatically. Supports PEP 668, CUDA version mismatches, missing system libraries, and many more common patterns.

What makes it different

No LLM required

The core engine is a rule-based system, not an AI wrapper:

• Extensive library of known projects with hand-crafted installation recipes
• Wide language coverage with intelligent type detection
• Comprehensive error-fix rules covering real-world installation failures
• LLM is optional — only used when the rule engine isn't confident

Zero dependencies

$ pip show gitinstall | grep Requires
Requires:

Pure Python standard library. No requests, no click, no rich. One pip install and it works. No dependency conflicts, ever.

Safety built-in

• Dangerous command patterns blocked (including encoding bypass attempts)
• SSRF protection on URL fetching
• No auto-sudo — prompts explicitly when root needed
• Smart failure detection — stops retrying when the error is unfixable

---

Also works as a CLI

gitinstall works standalone too, no AI agent needed:

gitinstall comfyanonymous/ComfyUI     # Install a project
gitinstall detect                      # Check your system
gitinstall doctor                      # System diagnostic
gitinstall audit pytorch/pytorch       # Security audit
gitinstall plan neovim/neovim          # Preview install plan

How It Works

User → AI Agent → MCP → gitinstall
                         ├── detect   → OS / GPU / runtimes / package managers
                         ├── plan     → intelligent multi-strategy planner
                         ├── execute  → safe subprocess execution
                         ├── fix      → error pattern matching → auto-retry
                         └── fallback → alternative install strategies

The planner uses a multi-tier strategy that combines project-specific knowledge, language-aware templates, and README analysis to generate optimal installation plans for a wide range of projects.
