Index dynamic Monte Carlo runs with this MCP Server

The `simulate_withdrawal_probabilities` tool generates survival rates that your LlamaIndex pipeline can immediately index into a vector database. This means past simulation runs become searchable context, allowing your agent to answer questions based on real historical math rather than guesswork. Instead of running new simulations for every user query, your agent queries the indexed results of previous runs. This dramatically reduces API overhead and speeds up response times for your users.

Ground financial advice in historical extremes

The `get_scenario_extremes` tool retrieves the absolute best and worst-case withdrawal amounts from historical data. LlamaIndex stores these extreme boundaries as document nodes, creating a permanent reference point for your agentic RAG system. When users ask about market crashes like the 1970s stagflation era, your agent retrieves these stored nodes to provide factual, numbers-backed answers. Your financial advisor agent stays grounded in historical reality.

Query asset volatility profiles semantically

The `evaluate_portfolio_risk_profile` tool analyzes asset mix volatility and feeds the resulting risk data directly into your query engine. This converts raw risk metrics into structured knowledge that your agent can search and summarize. By combining these live volatility metrics with indexed client documents, your agent delivers personalized asset allocation advice. The system matches the client's risk tolerance with the actual volatility profile of their portfolio.

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 Retirement Withdrawal Calculator tools.",
)
response = await agent.run("List recent Retirement Withdrawal Calculator data")

Common questions about Retirement Withdrawal Calculator MCP in LlamaIndex

Yes, you can convert the outputs of this MCP into document nodes. This allows your RAG application to search past simulation runs and use them as grounded context for user queries.

By querying the MCP directly, your agent pulls actual historical math and survival probabilities. LlamaIndex then injects these exact numbers into the prompt context, keeping the agent grounded.

Install the LlamaIndex MCP tool spec package and initialize the client with the server URL. You can then convert the client tools into standard LlamaIndex tools and pass them to your agent.

Yes, you can use the allowed tools filter during initialization to restrict access. This ensures your agent only calls the specific financial tools required for the current task.
