How to Use the Formsite MCP in LlamaIndex

Q: Can LlamaIndex index historical Formsite submissions?

Yes, your agent can call listresults to pull all past submissions and load them into a vector index. This allows you to perform semantic search over old form entries.

Q: Does the LlamaIndex integration support real-time Formsite updates?

You can use the createwebhook tool within LlamaIndex to set up real-time event listeners. This pushes new submissions directly to your indexing pipeline as they happen.

Q: What happens if my form has thousands of submissions?

The listresults tool supports pagination parameters to fetch data in chunks. Your agent will automatically page through the results to prevent memory issues in your runtime.

Index your Formsite submissions and webhooks directly into LlamaIndex vector stores for retrieval-augmented generation.

Semantic Search Over Form Submissions

The `list_results` and `get_form_details` tools fetch live submission data directly into your LlamaIndex pipeline. Your agent calls these tools to retrieve the raw text responses and metadata from your active forms. Once retrieved, LlamaIndex parses this data into document nodes and indexes them into your vector database. This lets you run semantic queries over historical submissions instead of relying on exact keyword matches.

Schema-Aware RAG with LlamaIndex MCP Server

This MCP Server exposes form structures through `list_form_items` to ground your agent's queries in actual schema definitions. The agent checks the question fields first, ensuring it only queries relevant data fields. By combining this structural data with `get_form_reports`, the agent answers complex analytical questions. It matches the user's intent to the correct report column, eliminating hallucinations about your form layout.

Dynamic Webhook Monitoring

Tracking your active data pipelines is managed using the `list_webhooks` and `create_webhook` tools. The agent queries existing integrations to verify where your form submissions are being routed. If a routing endpoint fails, the agent uses `delete_webhook` to tear down the broken hook and registers a new one. This keeps your real-time data ingestion pipelines running without manual intervention.

Setup guide

Set up Formsite MCP in LlamaIndex

Prerequisites

Python 3.10+ installed
llama-index-tools-mcp package
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install llama-index-tools-mcp llama-index-llms-openai. The MCP tools package provides BasicMCPClient and McpToolSpec.
2

Connect with BasicMCPClient
Point BasicMCPClient to your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports SSE and Streamable HTTP transports.
3

Convert to LlamaIndex tools
Call mcp_tool_spec.to_tool_list_async() to convert all Formsite MCP tools into native FunctionTool objects that any LlamaIndex agent can use.
4

Run with any LLM
Create a FunctionAgent with the tools and your preferred LLM. Swap OpenAI for Anthropic, Gemini, or any LlamaIndex-supported provider.

agent.py

from llama_index.tools.mcp import BasicMCPClient, McpToolSpec
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

# Connect to the MCP
mcp_client = BasicMCPClient(
    "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)
mcp_tool_spec = McpToolSpec(client=mcp_client)

# Convert MCP tools to LlamaIndex tools
tools = await mcp_tool_spec.to_tool_list_async()

# Create and run the agent
agent = FunctionAgent(
    tools=tools,
    llm=OpenAI(model="gpt-4o"),
    system_prompt="You have access to Formsite tools.",
)
response = await agent.run("List recent Formsite data")
