### Description (declared)

# leo-mcp

**Give your coding agent the real call graph of your repo, with proof,**
**instead of letting it guess by grepping and reading whole files.**

## Quickstart

leo-mcp is in beta, published on PyPI and npm:

```bash
uv tool install leo-mcp   # installs the leo-mcp command
leo-mcp doctor                  # checks your setup and prints the config snippet
claude mcp add leo-mcp -- leo-mcp   # Claude Code
```

Other clients: run `leo-mcp init --client opencode|cursor|codex` inside your project.

Requirements: [uv](https://docs.astral.sh/uv/), which fetches Python for you. Without uv: `pip install leo-mcp` with Python ≥ 3.11. Or without installing anything: `claude mcp add leo-mcp -- npx -y leo-mcp`.
No API key: leo-mcp never calls an LLM. It parses your repo locally.

## What your agent gets

Two tools, plus server instructions that tell the agent when to use them.

**`graph`** gives deterministic answers from the parsed call graph, each one cited `file:line`:

```
> graph op=who_calls symbol=get_session
[who_calls] get_session — 10 resu…
