Index Campaign History

Getting past performance data requires `list_sent_history` and `get_campaign_click_data`. Your LlamaIndex application pulls these metrics to build a searchable knowledge base of marketing results. Instead of guessing what worked last quarter, you query the index. The agent retrieves actual API data and grounds its answers in real click rates rather than hallucinated numbers.

Map Audiences in LlamaIndex

Mapping your audience requires raw contact structures. The `list_subscriber_collections` tool pulls your exact list definitions straight from the database. You combine this live API data with internal strategy documents. Your RAG setup now understands exactly who receives which message and why.

Stage Database Updates

Creating records uses `create_base_contact` and `add_contact_to_list`. The MCP Server executes these writes while updating your local context so the index stays fresh. When you ask the system to prepare a new send, it checks the index first. Then it stages the blast using `get_campaign_details` to verify the content.

Setup guide

Set up Mailsoftly 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 Mailsoftly 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 Mailsoftly tools.",
)
response = await agent.run("List recent Mailsoftly data")
