Create IDs for LlamaIndex vector entries

Use `generate_nanoid` to assign unique keys to your documents before they hit the vector store. It replaces bulky UUIDs with 21-character strings, saving space in your index. This ensures your LlamaIndex RAG application stays performant as it scales. You get consistent, URL-safe identifiers for every piece of indexed data.

Configure custom alphabets for LlamaIndex queries

You can define a custom alphabet for your IDs by calling `generate_nanoid` with specific parameters. It helps you maintain strict ID formatting across your entire knowledge base. This is vital when your LlamaIndex data needs to match specific database constraints. You define the rules, and the tool handles the generation logic.

Speed up LlamaIndex ingestion with MCP

This MCP Server is optimized for high-throughput ID generation. By using it, you reduce the time it takes to prepare data for your LlamaIndex ingestion pipelines. It provides a direct way to generate identifiers without external dependencies or heavy libraries. You get secure, random IDs every time you call the tool.

Setup guide

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

Common questions about Nanoid Generator MCP in LlamaIndex

You install the MCP client and add the Nanoid Generator server to your tool spec. LlamaIndex then exposes `generate_nanoid` as a function your agents can call during ingestion.

Yes, these IDs are ideal for document metadata and database keys. They are compact and URL-safe, which helps LlamaIndex maintain efficient index structures.

Yes, you can specify the size parameter when calling the tool. This allows you to fit IDs into any existing LlamaIndex schema or storage requirement.

The server uses cryptographic randomness to generate IDs. This ensures that your LlamaIndex data remains uniquely identified and protected against collisions.

The server only processes the generation request and returns the ID. It never touches your sensitive LlamaIndex source documents, ensuring your data privacy remains intact.
