How to Use the Forecast MCP in LangChain

Q: Can LangChain trace Forecast API calls in LangSmith?

Yes. Every time your agent calls listtasks or getproject, LangSmith records the latency, token count, and exact payload. You can monitor every automated resource decision.

Q: Can I combine this MCP server with other LangChain tools?

Yes. You can chain Forecast tools like listmilestones with external databases or communication tools in the same LangGraph pipeline.

Map LangChain Chains to Live Forecast Milestones

Your LangChain agents can now check team workloads before assigning new tickets. By linking `list_people` and `list_tasks` in a single chain, the agent matches active tasks with available staff without manual scheduling. This MCP server lets your agent make decisions based on actual availability. If a deadline shifts, the chain automatically pulls data from `list_milestones` to recalculate delivery windows. LangSmith traces every tool execution, giving you complete visibility into how the agent updates your project timeline.

Automate Client Status Reports via ReAct Agents

Run multi-step reasoning pipelines that group work by client. The agent calls `list_clients` to identify active accounts, then queries `list_projects` to pull their active initiatives. This MCP integration removes the need to write custom API wrappers for every project update. The agent processes these lists, summarizes progress, and flags delayed items. Since the MCP server provides direct access to `get_project`, your LangChain loops always operate on live, verified data.

Dynamic Resource Allocation Pipelines

Build chains that balance team capacity on the fly. When a new task enters your queue, the LangChain agent uses `list_tasks` to see what is already on everyone's plate. It compares this against team member lists from `list_people` to find the best assignee. This setup turns your static task tracker into an active scheduler. Because this MCP server runs in a secure sandbox, your team data remains protected while your agent organizes the backlog.

Setup guide

Set up Forecast MCP in LangChain

Prerequisites

Python 3.10+ installed
langchain-mcp-adapters + langgraph packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install langchain-mcp-adapters langgraph langchain-openai. The MCP adapters package converts MCP tools into native LangChain BaseTool objects.
2

Connect via HTTP transport
Use MultiServerMCPClient with "transport": "http" pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create a ReAct agent
Pass the discovered tools to create_react_agent() from LangGraph. The agent automatically routes Forecast tool calls through the MCP protocol.
4

Run with any LLM
Swap ChatOpenAI for ChatAnthropic, ChatGoogleGenerativeAI, or any LangChain-compatible model. The MCP tools work identically across all providers.

agent.py

from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain_openai import ChatOpenAI

async with MultiServerMCPClient({
    "forecast-mcp": {
        "transport": "http",
        "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp",
    }
}) as client:
    tools = client.get_tools()

    agent = create_react_agent(
        ChatOpenAI(model="gpt-4o"),
        tools,
    )
    result = await agent.ainvoke({
        "messages": "List recent Forecast transactions"
    })
    print(result["messages"][-1].content)
