Perplexity

Semantic knowledge indexing

Fetch live data using `execute_graphql` and immediately turn it into searchable vectors. It grounds your agent responses in real-time records rather than stale data. Use `explain_graphql` to optimize the queries you run against your index. This ensures your data retrieval is fast and accurate.

Database schema management

Use `execute_metadata` to update your engine settings directly from your indexing pipeline. It keeps your database structure in sync with your evolving knowledge base. Call `get_version` to confirm your infrastructure is compatible with your current LlamaIndex implementation. It helps avoid version-mismatch errors during ingestion.

Infrastructure monitoring

Verify your system health with `check_health` before running large-scale index updates. It prevents failures caused by temporary server downtime. Retrieve deep configuration settings with `get_config`. This gives your agent full visibility into the environment it is currently querying.

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 Hasura (Instant GraphQL & REST Engine) 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 Hasura (Instant GraphQL & REST Engine) tools.",
)
response = await agent.run("List recent Hasura (Instant GraphQL & REST Engine) data")
