scope-mcp 0.1.0

Give your AI coding assistant real code understanding — powered by the same engines VS Code uses

scope-mcp

A tool that gives your AI coding assistant superpowers. Instead of guessing what your code does, it gets real answers straight from the same engines VS Code uses — so it actually understands functions, classes, types, and where things connect.

No setup. No indexing. Just works.

What's the problem?

When you ask an AI to "find where get_lsp is called," most tools do a text search — like Ctrl+Shift+F. That returns everything named get_lsp: the definition, comments, imports, false positives. You have to dig through the noise.

┌─ grep (text search) ─────────────────────┐
│  project.py:75  def get_lsp(self, lang)   │  ← definition (not a call)
│  project.py:110 return await get_lsp(lang)│  ← actual call
│  project.py:117 lsp = await get_lsp(lang) │  ← actual call
│  project.py:81  cfg = LSP_REGISTRY...     │  ← noise
│  project.py:109 async def get_lsp_for...  │  ← noise
│    5 results · 3 are noise                │
└───────────────────────────────────────────┘

┌─ scope (smart search) ────────────────────┐
│  [call site] project.py:110               │
│  [call site] project.py:117               │
│    2 results · 0 noise                    │
└───────────────────────────────────────────┘

Scope asks the compiler instead. You get only what you actually asked for.

What you can do with it

Instead of digging through files...	Just ask scope...	You get
Grepping for a function name and filtering out junk	find_references("get_lsp")	Only the places where it's actually called — no noise
Reading a whole file to figure out what's in it	explain_file("server.py")	A clean summary: language, line count, every function and class
Hunting through 50 files to find where an interface is used	implementations("IEventHandler")	One answer with all the implementations
Tracing who calls what by hand	call_hierarchy("validate_token")	A tree of callers and callees, 3 levels deep
Scanning a big diff to see what changed	changed_since("HEAD~3")	Just the changed files and affected symbols

How it works

1. Scope looks at your project — it spots what languages you're using (Python, TypeScript, Rust, Go, C++) from files like package.json or Cargo.toml.
2. It sets up the brain — launches the same language engine your editor uses (pyright, tsserver, rust-analyzer, gopls). If missing, it installs one automatically.
3. Your AI asks, scope answers — every question hits that engine live. No stale data, no sync jobs, no waiting.

AI Assistant (Claude, Codex, etc.)  ←→  scope  ←→  Language Engine

Setup

pip install scope-mcp

Then add one line to your AI client's config:

Claude Desktop / Code

{
  "mcpServers": {
    "scope": {
      "command": "scope",
      "args": ["--project", "."]
    }
  }
}

Any AI coding tool

command:  scope
args:     ["--project", "/path/to/your/project"]
transport: stdio

From source

git clone https://github.com/yourname/scope-mcp
cd scope-mcp
pip install -e .

Optional extras: rg (ripgrep) for text searches, git for change tracking.

Languages scope understands

Language	Detected when it sees...	Scope handles setup
Python	pyproject.toml · setup.py · requirements.txt	✅ Installs pyright automatically
TypeScript / JavaScript	tsconfig.json · package.json	✅ Installs tsserver automatically
Rust	Cargo.toml	✅ Installs rust-analyzer automatically
Go	go.mod	✅ Installs gopls automatically
C / C++	CMakeLists.txt · compile_commands.json	⚠️ You install clangd manually

Requirements

• Python 3.11 or newer
• ripgrep (optional, for text search)
• git (optional, for change tracking)
