📅 ForexFactory MCP Server

An MCP (Model Context Protocol) server that exposes ForexFactory economic calendar data as resources and tools.

Designed for use in agentic workflows, LLMs, and trading assistants.

🚀 Features

• ✅ Retrieve economic calendar events by time period (today, this_week, custom, etc.)
• ✅ Access via MCP resources (for subscription-style access)
• ✅ Access via MCP tools (direct calls from clients/agents)
• ✅ JSON-first responses for easy integration
• ⚡ Integrates with LangChain, n8n, or any MCP-compatible client

📌 Development Status

This project is actively developed. The core functionality is stable (retrieving ForexFactory economic calendar events via MCP tools and resources), but we are still:

• Expanding features (prompts, deployment options)
• Improving documentation and examples

We welcome feedback and contributions while we continue building out the ecosystem.

▶️ Usage

⚡ Quickstart

Start the server with default settings (stdio transport):

uv run ffcal-server

Run with HTTP transport:

uv run ffcal-server --transport http --host 0.0.0.0 --port 8080

SSE transport (⚠️ deprecated)

uv run ffcal-server --transport sse --host 127.0.0.1 --port 8001

Environment variable defaults

MCP_TRANSPORT=http
MCP_HOST=0.0.0.0
MCP_PORT=8080

🏷️ Namespace

Default namespace:

ffcal

Override via .env:

NAMESPACE=ffcal

📦 Resources

🛠️ Tools

Supported values:

See the Output Style Reference for available formats.

💻 Client Examples

Example: Using MCP CLI

mcp call ffcal:get_calendar_events time_period=this_week

Example: Using in Python

from mcp.client.session import Session
async with Session("ws://localhost:8000") as session:
    result = await session.call_tool("ffcal:get_calendar_events", {"time_period": "today"})
    print(result)

Example: LangChain Integration

from langchain.agents import initialize_agent
from langchain_mcp import MCPToolkit

toolkit = MCPToolkit.from_server_url("ws://localhost:8000", namespace="ffcal")
agent = initialize_agent(toolkit.tools)
response = agent.run("What are today's USD-related high impact events?")
print(response)
