How to Use the Gravity Forms MCP in LangChain

Q: How do I pass Gravity Forms schemas into a LangChain chain?

You call getform using the Gravity Forms MCP Server inside your client initialization. This returns the exact JSON structure of your fields, which you can pass directly to a prompt template or use to configure dynamic input validation in your LangChain chain.

Q: Can a LangChain agent delete entries in Gravity Forms?

Yes, the agent can call deleteentry if you grant it write permissions. You just configure the tool within your LangChain agent's toolbelt, and it will execute the deletion whenever your chain logic flags an entry for removal.

Q: Can I manage form notifications programmatically?

Yes, you can use getnotifications to retrieve the current email alerts configured for any form. This lets your agent check if the right routing rules are active before submitting new data.

Chain your Gravity Forms data directly into LangChain runs to inspect entries, create notes, and handle submissions without custom API code.

Chain form data directly into LangChain pipelines

The `list_forms` MCP tool lets your LangChain agent pull your active WordPress forms directly into a multi-step execution chain. We built this so you can inspect form layouts using `get_form` and feed those structures directly to your LLM to map out incoming user fields. You don't have to write custom wrappers to pass these schemas to subsequent steps. The agent takes the form schema, validates user inputs, and passes them to `submit_form` to programmatically register leads while LangSmith tracks every tool execution.

Run multi-step entry analysis with LangSmith tracing

The `list_entries` tool fetches raw form submissions so your LangChain agent can analyze user data and automatically append context. By passing these inputs through a reasoning chain, the agent identifies urgent submissions and immediately triggers `create_entry_note` to flag them for your support team. This setup helps you monitor complex workflows without losing visibility. LangSmith logs every single call to `list_entries` and `get_entry`, showing you the exact latency and token usage of your WordPress database operations.

Automate feed checks with this LangChain MCP Server

The `list_feeds` tool lets your LangChain agent inspect active integrations and notifications to ensure your WordPress form data flows where it should. Your agent can call `get_notifications` to verify that confirmation emails are set up correctly before updating records. If a user changes their submission, the agent runs `update_entry` to sync the database and runs a follow-up chain to verify the change. It handles the state changes in a single session, preventing broken data pipelines without manual intervention.

Setup guide

Set up Gravity Forms 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 Gravity Forms 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({
    "gravity-forms-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 Gravity Forms transactions"
    })
    print(result["messages"][-1].content)
