alpha-forge-mcp 0.1.0a4

MCP server (stdio) exposing the AlphaForge `forge` CLI to Claude Code / Cursor / Codex

alpha-forge-mcp

A Model Context Protocol (MCP) server that exposes the AlphaForge alpha-forge CLI to AI coding agents — Claude Code, Cursor, Codex, and any MCP-capable client — over stdio.

⚠️ Pre-release / Alpha (0.1.0aN). Tool signatures and return formats may change without notice. Not recommended for production automation yet. Feedback welcome via Issues.

It is a thin open-source wrapper: it shells out to the (commercial, closed-source) alpha-forge binary with --json and returns the parsed result. The MCP server itself contains no core logic — alpha-forge plus a valid license are required for anything to actually run.

Tools

Tool	What it does	Underlying command
list_strategies	List registered strategies	alpha-forge strategy list --json
get_strategy	Full JSON of one strategy	alpha-forge strategy show <id> --json
list_results	List saved backtest results	alpha-forge backtest list [--strategy <id>] --json
get_result	Metrics & trades of one result	alpha-forge backtest report <result_id> --json
run_backtest	Run a backtest	alpha-forge backtest run <symbol> --strategy <id> [--start] [--end] --json
run_optimize	Optimize parameters (Optuna)	alpha-forge optimize run <symbol> --strategy <id> [--metric] [--trials] --json
generate_pinescript	Generate Pine Script v6 source	alpha-forge pine preview --strategy <id> [--with-webhook]

Streamable HTTP transport, RBAC, rate limiting, and audit logging are planned for a later release.

Prerequisites

1. The alpha-forge binary must be installed and on your PATH (or set ALPHA_FORGE_BIN).
2. You must be authenticated: run alpha-forge system auth login once.
3. Python 3.11+ (only needed if not using uvx).

Install & run

The recommended way is via uvx — no manual install needed; your IDE launches it on demand.

uvx alpha-forge-mcp        # starts the stdio MCP server

Or install explicitly:

pip install alpha-forge-mcp
alpha-forge-mcp

Claude Code

The easiest way is the claude mcp add command (user scope — available in every project):

claude mcp add --scope user alpha-forge -- uvx alpha-forge-mcp

Alternatively, add the server to a project-scoped .mcp.json at the repository root (checked in and shared with your team):

{
  "mcpServers": {
    "alpha-forge": { "command": "uvx", "args": ["alpha-forge-mcp"] }
  }
}

Note: Claude Code does not read ~/.claude/mcp.json. User-scoped servers are stored in ~/.claude.json (managed by claude mcp add); project-scoped servers live in .mcp.json at the project root.

Cursor / Codex

Use the same command / args in the client's MCP server configuration:

{
  "mcpServers": {
    "alpha-forge": { "command": "uvx", "args": ["alpha-forge-mcp"] }
  }
}

If alpha-forge is installed at a non-standard location, pass it via env:

{
  "mcpServers": {
    "alpha-forge": {
      "command": "uvx",
      "args": ["alpha-forge-mcp"],
      "env": { "ALPHA_FORGE_BIN": "/path/to/alpha-forge" }
    }
  }
}

Troubleshooting

• forge_not_found — ensure alpha-forge (or legacy forge) is on PATH, or set ALPHA_FORGE_BIN=/path/to/alpha-forge.
• authentication_required — run alpha-forge system auth login. The MCP server does not store credentials; it relies on alpha-forge's own auth.

Development

uv sync --extra dev
uv run pytest
uv run ruff check .

Forge binary discovery order: ALPHA_FORGE_BIN → PATH (forge, alpha-forge) → OS default install paths.
