安装与配置
- 复制上面的命令
- 粘成
claude_desktop_config.json里mcpServers的一项（本地服务器用 command + args，示例见 客户端接法） - 重启客户端
客户端配置（取自该仓库的安装命令）
{
"mcpServers": {
"frowningdev-orm-lens": {
"command": "uvx",
"args": ["orm-lens"]
}
}
}解析自我们于 2026-11-04 抓取的该仓库 README；我们未执行过。
command/args 来自仓库写明的安装命令；不确定时请以该项目 README 为准。
VS Code（.vscode/mcp.json —— 键名是 servers）
{
"servers": {
"frowningdev-orm-lens": {
"command": "uvx",
"args": ["orm-lens"]
}
}
}VS Code 顶层键是 <code>servers</code>，其余与上面那份相同。
Claude Code（命令行）
claude mcp add --transport stdio frowningdev-orm-lens -- uvx orm-lens
Claude Code 不收 JSON 文件，用这条命令直接加。
配置项的键名以你的客户端为准：客户端与 CLI

# ORM Lens
### ER diagrams, N+1 detection and migration-risk checks for Django and SQLAlchemy — without booting either.
Your entire model graph — live in your editor sidebar, gating your CI, and answering your AI agent over MCP. All from static parsing: no database, no runserver, no working venv. Django models and migrations, SQLAlchemy models and Alembic revisions.
Formerly django-orm-lens. pip install django-orm-lens still works and installs orm-lens.
Replaces: graphmodels + django-schema-graph + hand-drawn ER diagrams + grep archaeology.
Featured in Django News #347 · PyCoder's Weekly #746
## ⚡ 10 seconds to first insight
bash
uvx orm-lens scan -f table # every app and model at a glance
uvx orm-lens nplusone # N+1 loops, with the selectrelated / selectinload to add
uvx orm-lens migration-risk # Django migrations and Alembic revisions that lock tables or fail
Cold clone, broken venv, no settings module — you still see every app and model of the project, then the N+1 loops and risky migrations in it, right in your terminal. (uvx is from uv; pipx run works the same way.)
Then pick your surface — three distributions, one parser core:
| You are | Install | You get |
| Editor user (Django) — VS Code / Cursor / Windsurf / VSCodium | code --install-extension frowningdev.django-orm-lens | Field autocomplete in .filter(), sidebar tree, live ER diagram, hover cards, 18 lint rules with QuickFixes |
| Terminal / CI user | pip install orm-lens | 17 subcommands, SARIF + PR annotations, pre-commit hooks, a GitHub Action |
| AI-agent user — Cursor / Claude Code / Aider / Zed / Continue | pip install "orm-lens[mcp]" | 14 read-only MCP tools answering schema questions from ground truth |
MCP setup is one JSON block — see Integrations. Point ORMLENSROOT at your project's absolute path.
## 🆓 Paid-tier capabilities, free and MIT
Schema review is a paid category nearly everywhere. A bot that reviews every pull request, analysis that follows a queryset past the function it was built in, a check that catches schema drift, index advice grounded in real table statistics — those normally sit behind a per-seat or per-database subscription.
All of it is here, MIT-licensed, with no tier gate, no seat count, no account, and no telemetry:
| Capability usually sold as a paid tier | Here |
| PR review bot for schema changes — posts once, then updates in place | blast-radius + the Action |
| Analysis that follows a queryset across functions | nplusone |
| Schema drift detection | drift |
| Index proposals from observed QuerySet usage | suggest-indexes |
| Migration risk weighed against real table sizes | blast-radius --stats |
| Blast radius of a destructive migration | blast-radius |
| Cross-layer impact of removing a field | impact |
There is no Pro tier, and none is planned. If the tool saves you an afternoon, a star is the entire ask.
## 📊 Traction
> If the tool saves you a grep next time you touch a strange Django project — a star helps others find it.
