How to Use the Yousign MCP in LlamaIndex

Q: Can LlamaIndex track signature changes?

Absolutely. By indexing the results of getsignaturerequest and listsignaturerequests, you build a history log. You can query specific changes or status updates from past sessions.

Q: Does Yousign support LlamaIndex for multi-signer requests?

Yes. The tool calls like addsignertorequest define the participants, and LlamaIndex indexes this roster information alongside the document details in your knowledge base.

Q: What if I need to find old contact info with Yousign and LlamaIndex?

You use listyousigncontacts to get the raw data, which is then indexed. You can search across historical contacts without needing to know the exact name or ID.

Perplexity

Build Searchable Signature History

The output of Yousign tools becomes indexed knowledge. You run `list_signature_requests` and index the results. Later, you can query your vector store—not just asking if a request exists, but getting context about its status.

Track Document Metadata Over Time

When you use `add_document_to_request`, that metadata gets stored. LlamaIndex indexes this data, letting you search across past signings and configs. You query the 'why' behind a signing process.

Deep Dive into Account Details

Need to know account limits or workspace settings? Call `get_workspace_details`. This information gets indexed, allowing you to build RAG applications that answer questions about your overall Yousign setup.

Setup guide

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