Perplexity

Build a searchable knowledge base with Mela

Use LlamaIndex to index output from `list_activities` and `get_activity` into a vector store. You can query your entire project history using natural language instead of digging through individual logs. This turns your static site reports into an active asset. Your agent retrieves context from past site visits to answer questions about current resource consumption.

Ground AI answers in Mela API data

Combine live `log_materials` entries with your existing documentation in a unified index. Your agent provides answers based on actual consumption rates rather than guessing. This reduces hallucinations by forcing the agent to reference the specific data points you provided. It's the most reliable way to maintain project accuracy over time.

Query Mela resources with LlamaIndex

Configure your client to include resources like project notes and checklists automatically. The index keeps these files current, so your agent always looks at the latest site information. This means your RAG application stays in sync with your field teams. When they update a status, your index reflects it immediately for the next query.

Setup guide

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

Common questions about Mela MCP in LlamaIndex

You use the BasicMCPClient to fetch data from the server and pass it to the indexing layer. LlamaIndex then converts this data into embeddings for semantic retrieval.

Yes. Use the allowed_tools filter to limit which parts of the Mela API your agent can access. This keeps your project data safe and focused.

Your job site logs and accounting data are stored locally in your vector store. Vinkius ensures secure transport, but you retain full control over your stored embeddings.

It does. By using McpToolSpec, you can convert Mela functionality into tools that your FunctionAgent invokes whenever it needs fresh project data.

Since LlamaIndex queries the MCP Server directly, your agent pulls the latest state. You can refresh your index periodically to capture updates from the field.
