PineForge — offline PineScript v6 backtest MCP server

@pineforge/backtest-mcp

Self-contained stdio MCP server: an AI agent writes PineScript v6, and the bundled pineforge-release image transpiles it to C++ and backtests it against Binance market data — all in one container, in-process. Fully local — the image bundles the pineforge-codegen transpiler, so Pine → C++ → backtest run with no host Docker daemon. No API key, nothing leaves the box.

Tools

Install

Runs as a self-contained container over stdio — engine bundled, in-process, no host Docker daemon, no API key. Mount a working dir at /work so the server can read/write your CSVs:

docker run --rm -i -v "$PWD:/work" ghcr.io/pineforge-4pass/pineforge-backtest-mcp:latest

Only requirement: Docker, and outbound network for the Binance fetch tools. Wire it into your MCP client below.

Hosted (no-install) alternative

Want the fastest try with no Docker and no API key? Paste the Streamable HTTP endpoint into any MCP client:

https://mcp.pineforge.dev/mcp

Tradeoff vs this repo: the hosted server is metered (per-IP weekly quota on backtestpine + Cloudflare edge rate-limiting) and runs against a fixed, sealed crypto data-lake (Binance spot + USDT-perp). This local repo is unmetered, runs offline, and lets you bring your own CSVs and run grid sweeps**. Repo: pineforge-mcp-public.

Client configuration

Mount a directory at /work; point fetchbinanceohlcv / backtest_pine at paths under it. (-i is required; never add -t — a TTY corrupts the stdio JSON-RPC stream.)
