pineforge
For AI assistants · free hosted MCP + local Docker

Backtest Pine strategies from Claude, Cursor, or any MCP client.

Two ways to connect: (1) free hosted endpoint — Streamable HTTP at https://mcp.pineforge.dev/mcp, no install, no key, 100 backtests/week, last 13 months of crypto data; (2) local Docker — bring your own OHLCV, engine bundled, nothing leaves your machine.

Hosted (fastest start)No Docker, no install. Free — 100 backtests/week per IP. Last 13 complete months of crypto OHLCV included. Join the waitlist to unlock the API-key tier (full history + higher limits).Local Docker (your own data)Requires Docker. Mount a working dir at /work for your CSVs — no API key, the engine is bundled in the image.

Requires Docker. Mount a working dir at /work for your CSVs — no API key, the engine is bundled in the image.

Local Docker (your own data)
docker run --rm -i -v "$PWD:/work" ghcr.io/pineforge-4pass/pineforge-codegen-mcp:latest

Privacy

Hosted: your Pine source is sent to mcp.pineforge.dev for backtesting; OHLCV is served from our dataset — no local files needed.

Your Pine source and OHLCV never leave your machine — transpile and backtest both run inside the container, offline. No API key, nothing crosses the network.

Works with any MCP-aware client.

Claude Desktop

Add to your claude_desktop_config.json (Settings → Developer → Edit Config). No API key — the engine is bundled in the image.

claude mcp add --transport http pineforge https://mcp.pineforge.dev/mcp
Local Docker (your own data)
claude mcp add pineforge-local \
  -- docker run --rm -i -v "$PWD:/work" ghcr.io/pineforge-4pass/pineforge-codegen-mcp:latest

Cursor

Settings → MCP → New MCP Server → paste the Claude Desktop JSON config above.
