How to Use the GRIN MCP in LlamaIndex

Q: How does LlamaIndex prevent hallucinated metrics when reading GRIN data?

The framework indexes the raw tool outputs from listconversions directly into your vector store. This ensures the agent only answers queries using verified, grounded numbers from the server.

Q: Can I filter which influencer tools are exposed to the index?

Yes, you can use the allowedtools filter during initialization. This lets you restrict the agent to reading data via listcontacts while blocking modification tools.

Index live GRIN creator metrics directly into your LlamaIndex vector store for semantic search.

Perplexity

Build a searchable knowledge base of creator content

Stop digging through folders to find high-performing influencer posts. By connecting this MCP Server to LlamaIndex, you can pull creator assets via `list_content` and index them directly into your vector database. Users can query the index using natural language to find specific imagery or captions. Your agent searches the grounded index to answer questions about which creators match your current brand aesthetic.

Ground campaign reports in real financial data

Avoid AI hallucinations when reviewing campaign performance and ROI. LlamaIndex pulls real-time numbers using `list_conversions` and `list_payments` to back up its summaries with actual spend and sales data. This approach ensures your agent only references verified figures. The system queries the index of past sessions to build accurate reports on influencer profitability without guessing.

Search your creator CRM semantically using LlamaIndex

Find the right influencer for your next campaign by searching your actual CRM data. The framework uses `list_contacts` and `get_contact` to pull creator profiles, turning flat database rows into searchable text nodes. You can search for creators based on qualitative notes or past performance history. This turns your static GRIN database into an active, queryable asset for your marketing team.

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