How to Use the Constant Contact MCP in LlamaIndex

Q: Can I build a RAG pipeline using Constant Contact metrics in LlamaIndex?

Yes, you can run getcampaignstats to pull raw engagement data and index it directly into your vector store. This allows your agent to answer questions about email performance using grounded, real-time metrics.

Q: Does LlamaIndex support filtering which Constant Contact tools are exposed?

Yes, you can use the allowedtools filter when setting up your McpToolSpec. This lets you restrict your agent to safe tools like listmailinglists while blocking write tools.

Q: How does this MCP Server secure my Constant Contact campaign configuration data?

All campaign configuration details retrieved by getcampaigndetails are processed in a zero-trust, ephemeral V8 sandbox. Vinkius never stores your marketing content or API keys on persistent disks.

Index your Constant Contact marketing data directly into LlamaIndex vector stores for hallucination-free RAG.

Index Constant Contact campaign metrics with LlamaIndex

`get_campaign_stats` retrieves performance figures that your LlamaIndex pipeline indexes into a local vector store. This turns raw open rates and click counts into a searchable knowledge base your agent can query. Instead of guessing which email did well, your agent queries the index to find past campaigns with high engagement. It pulls active context from actual metrics to ground its answers, completely eliminating hallucinated stats.

Query subscriber profiles using vector search

`get_contact_details` extracts custom fields and list memberships to build a local index of your audience structure. Your agent searches this index to find patterns in subscriber behavior without hitting the live API repeatedly. If you need to find specific segments, the agent queries the index using natural language. It matches the user's intent against indexed records retrieved by `list_contacts` to find target profiles instantly.

Retrieve exact campaign settings

`get_campaign_details` fetches the raw subject lines and sender profiles to feed your retrieval-augmented generation pipeline. This ensures your agent has the exact historical context of your marketing setup. This MCP Server allows your LlamaIndex agent to cross-reference active campaign configurations with your subscriber lists. You get a unified index that merges live API data with your existing text documents.

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.

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 Constant Contact 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 Constant Contact tools.",
)
response = await agent.run("List recent Constant Contact data")
