Price sovereign debt across your CrewAI agents

Your research agent pulls the coupon and maturity dates. It passes those to `calculate_bond_valuation` to get the fair market price and yield to maturity. The math handles semi-annual payments automatically. You do not need to babysit the cash flow projections. The agent spits out the annualized total return and moves on to the next ticker. Just make sure your input yields are current, or your pricing will be garbage.

Compare cross-border yields without FX headaches

Comparing UK Gilts to US Treasuries means dealing with currency risk. Your analysis agent uses `calculate_currency_equivalent_yield` to convert foreign sovereign yields into your target currency. It factors in the spot rate and cross-currency basis swaps. This stops your portfolio managers from chasing phantom yield just because a foreign bond looks cheap in nominal terms. The crew gets a clean apples-to-apples number. Keep an eye on the FX inputs, though, since stale rates ruin the conversion.

Track real purchasing power in autonomous workflows

Nominal yields lie when inflation spikes. Your risk monitor agent calls `calculate_inflation_adjusted_return` to strip out the CPI noise and show the actual purchasing power preservation. It subtracts the relevant inflation index from the nominal yield. You will see exactly how much real return you are getting on those German Bunds. The agent flags negative real yields before they blow up your liability-driven strategies. Do not ignore the inflation data lag, or you will be trading on yesterday's news.

Setup guide

Set up Treasury Return Calculator MCP in CrewAI

Prerequisites

Python 3.10+ installed
crewai package (pip install crewai)
Active Vinkius subscription with a valid endpoint token

1

Install CrewAI
Run pip install crewai to install the framework. MCP support is built-in via the mcps parameter.
2

Add the MCP URL to your agent
Pass your Vinkius endpoint directly to the mcps list. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. CrewAI handles tool discovery and caching automatically.
3

Kick off your crew
Create a Crew with your agent and tasks. Call crew.kickoff() — the agent will automatically invoke Treasury Return Calculator tools as needed.

crew.py

from crewai import Agent, Task, Crew

agent = Agent(
    role="Treasury Return Calculator Analyst",
    goal="Access and analyze Treasury Return Calculator data via MCP.",
    backstory="Expert analyst with direct Treasury Return Calculator access.",
    mcps=[
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ],
)

task = Task(
    description="List recent Treasury Return Calculator transactions",
    agent=agent,
    expected_output="A summary of recent activity",
)

crew = Crew(agents=[agent], tasks=[task])
result = crew.kickoff()
print(result)

Prerequisites

Python 3.10+ installed
crewai + crewai-tools packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install crewai crewai-tools. The MCPServerAdapter handles lifecycle management and tool conversion.
2

Connect with MCPServerAdapter
Use MCPServerAdapter as a context manager with SseServerParameters pointing to your Vinkius endpoint. The adapter automatically manages connection lifecycle.
3

Assign tools and run
Pass the returned mcp_tools to your agent's tools parameter. The adapter converts MCP tools to native BaseTool objects compatible with all CrewAI agents.

crew.py

from crewai import Agent, Task, Crew
from crewai_tools import MCPServerAdapter
from mcp import SseServerParameters

server_params = SseServerParameters(
    url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)

with MCPServerAdapter(server_params) as mcp_tools:
    agent = Agent(
        role="Treasury Return Calculator Analyst",
        goal="Access and analyze Treasury Return Calculator data via MCP.",
        backstory="Expert analyst with direct Treasury Return Calculator access.",
        tools=mcp_tools,
    )

    task = Task(
        description="List recent Treasury Return Calculator transactions",
        agent=agent,
        expected_output="A summary of recent activity",
    )

    crew = Crew(agents=[agent], tasks=[task])
    result = crew.kickoff()
    print(result)

Common questions about Treasury Return Calculator MCP in CrewAI

Install the framework via pip and pass the MCP URL directly into your agent's mcps list. For granular control, use the HTTP class from the framework's tools module with a tool filter to expose only the specific bond math tools you need.

Yes, the MCP handles concurrent requests from your entire agent team without breaking a sweat. Your research and analysis agents can query bond valuations in parallel during hierarchical execution. Just monitor your API rate limits if you are pricing a massive book of securities.

It uses standard consumer price indices to adjust nominal returns automatically. Your agents cannot currently feed custom or proprietary inflation metrics into the calculation. You will have to do that math manually outside the MCP if you need bespoke indices.

The MCP rejects the request and throws a validation error back to your agent. It will not attempt to guess the cash flow schedule for a bond that does not exist. Fix your agent's input parameters and try again.

It processes yield curve inputs, FX spot rates, cross-currency basis swap adjustments, and consumer price index data to calculate bond metrics. The MCP does not store your portfolio holdings or proprietary trading strategies after the calculation finishes. Your input parameters are ephemeral and wiped from memory immediately.
