Build automated chains with GivingFuel data

Feed your LangChain agents raw data from `list_donation_orders` to trigger downstream actions. You can process specific transactions as they hit your system, ensuring your logic follows the exact flow of funds. Connect these results to other vector stores or databases within your chain. By piping outputs from `list_recent_donations` directly into your next task, you remove manual steps and keep your workflow strictly code-driven.

Monitor your MCP Server with LangSmith

Track every tool call from your MCP Server using native LangSmith tracing. You'll see exactly how your agent handles inputs from `list_financial_transactions` and where your logic might bottleneck. This visibility lets you debug complex multi-step reasoning chains. If an agent fails to parse a donor record from `list_crm_contacts`, you have the full input/output logs to fix it immediately.

Execute multi-step fundraising workflows

Orchestrate complex logic by combining multiple tools in a single ReAct loop. Your agent can call `list_fundraising_pages` first, then decide to query `list_peer_campaigns` based on the active event status. This approach lets the agent determine the order of operations based on real-time data. You define the constraints, and the agent handles the heavy lifting of calling the right endpoints when needed.

Setup guide

Set up GivingFuel 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 GivingFuel 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({
    "givingfuel-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 GivingFuel transactions"
    })
    print(result["messages"][-1].content)

Common questions about GivingFuel MCP in LangChain

Install the necessary adapters and initialize the client using your endpoint URL. Pass the tools retrieved from the MCP Server directly into your agent constructor to start executing queries.

Yes, you can implement custom backoff logic within your agent's chain. Since you control the pipeline, you can catch rate-limit errors from the API and retry the specific tool call.

The server is stateless by default. You should use the client session feature to maintain context across multiple interactions if your specific use case requires it.

Data is transmitted over encrypted channels directly to your agent. Vinkius manages the secure endpoint, ensuring your API keys are never exposed in your application code.

The agent will receive an error response from the tool. You can configure your chain to catch this exception and either provide a fallback value or terminate the process gracefully.
