How to Use the Headscale (Tailscale Alternative) MCP in LlamaIndex

Q: Can LlamaIndex search through Headscale (Tailscale Alternative) nodes?

Yes, the agent retrieves node data via listnodes and embeds it into your vector store. This allows for semantic search across your entire machine inventory.

Q: How are tools filtered for LlamaIndex agents?

You define an allowedtools list when setting up your tool spec. This restricts the agent to only the operations you permit, such as read-only node listing.

Index your entire private network state into LlamaIndex for semantic search and grounded infrastructure reasoning.

Index network state with LlamaIndex

Turn your network configuration into a searchable knowledge base. By using `list_nodes` and `get_node`, LlamaIndex stores the current state of your mesh in a vector store for fast retrieval. Stop guessing which nodes are active. Query your index to find specific machine details or verify connectivity settings across your entire deployment.

Grounded network queries in LlamaIndex

Build RAG applications that answer questions about your infrastructure based on live data. The agent uses `list_routes` to gather current routing information before answering queries about traffic flow. Your answers are never hallucinations because they originate from your actual Headscale instance. The agent pulls data via tool calls and feeds it directly into your retrieval pipeline.

Manage users and keys via LlamaIndex

Control your user namespace through natural language queries. Tell your agent to provision a new user, and it will call `create_user` to update your network registry. Keep track of your API keys by indexing them with `list_api_keys`. If you need to audit access, simply ask the agent to find and expire old keys using `expire_api_key`.

Setup guide

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