# Snowfakery MCP Server

**Power up your AI workflows with Snowfakery data generation** — Use Claude, ChatGPT, and other AI assistants to author, debug, and run data recipes through the [Model Context Protocol](https://modelcontextprotocol.io/).

## What is this?

[Snowfakery](https://github.com/SFDO-Tooling/Snowfakery) is a YAML-based tool for programmatically generating test data. This MCP server connects Snowfakery to AI assistants, letting you:

- **Draft recipes** with AI assistance backed by real Snowfakery docs and examples
- **Validate recipes** before running them with detailed error feedback
- **Execute recipes** and iterate on results interactively
- **Debug issues** with static analysis and recipe inspection
- **Generate Salesforce mappings** for CumulusCI workflows

Perfect for teams that need realistic test data—from Salesforce admins to developers building data pipelines.

## Quick Start

### Install & Run

```bash
# Recommended: isolated install
pipx install snowfakery-mcp

# Then run the server
snowfakery-mcp
```

Or from source:

```bash
git clone https://github.com/composable-delivery/snowfakery-mcp.git
cd snowfakery-mcp
uv sync
uv run snowfakery-mcp
```

### Connect to Claude (Desktop)

Add to your Claude Desktop `claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "snowfakery-mcp": {
      "command": "snowfakery-mcp"
    }
  }
}
```

Then ask Claude:
> "Show me an example Snowfakery recipe" or "Help me write a recipe to generate 100 Salesforce accounts"

## Features

**Resources** — Access docs, examples, and schemas:
- Snowfakery documentation and recipe examples
- JSON schema for recipe validation
- Run outputs and artifacts

**Tools** — Interact with recipes:
- Validate & analyze recipes (catch errors early)
- Run recipes and capture output
- List & retrieve example recipes
- Generate CumulusCI mapping files

## Development

```bash
# Install dev dependencies
uv sync --all-groups

# Run tests
uv run pytest

# Type check
uv run mypy snowfakery_mcp

# Lint & format
uv run ruff check snowfakery_mcp tests scripts evals
uv run ruff format snowfakery_mcp tests scripts evals
```

### Evals (Agentic Testing)

This repo includes `inspect-ai` tasks for testing the MCP server with AI models:

```bash
# Install eval dependencies
uv sync --group evals

# Run evaluation
uv run inspect eval evals/inspect_tasks.py@snowfakery_mcp_agentic --model openai/gpt-4o-mini
```

See [evals/](evals/) for more examples and troubleshooting.

## Notes

- The repo includes the upstream Snowfakery repo as a git submodule (`Snowfakery/`) for development
- When running from source, use `uv run ...` to ensure the pinned environment
- PyPI installs use bundled docs/examples (no submodule required)

## Releases

See [GitHub Releases](https://github.com/composable-delivery/snowfakery-mcp/releases) for sdist, wheel, and experimental `.mcpb` bundles.
