  <strong>Give your coding agent (Claude Code, Cursor) reliable, always-fresh knowledge
  of your Dataform pipeline — table and column lineage, schemas, impact analysis —
  instead of letting it read <code>.sqlx</code> files one by one and hallucinate the DAG.</strong>

## Install with Claude Code

Prerequisites (once per machine): [uv](https://docs.astral.sh/uv/) (`brew install uv`)
and `@dataform/cli` ≥ 3.0 (`npm i -g @dataform/cli`).

At the root of **your Dataform repo**, create or extend `.mcp.json`
(template: [`.mcp.json.example`](.mcp.json.example)):

```json
{
  "mcpServers": {
    "dataform-context": {
      "type": "stdio",
      "command": "/opt/homebrew/bin/uvx",
      "args": ["--from", "dataform-context-mcp@latest", "dataform-context", "serve"]
    }
  }
}
```

That's it: no clone, no `--repo` (the server indexes the current directory). Open a
Claude Code session in the repo and type `/mcp`: `dataform-context` should show as
connected. First call takes ~15 s (initial compilation), then ~10 ms.

> [!IMPORTANT]
> **Absolute path to `uvx` is required**: a bare `"command": "uvx"` fails (`ENOENT`)
> when the agent is launched from a non-login shell whose PATH…
