How to Use the Expensya MCP in CrewAI

Q: How do I configure the Expensya MCP Server inside a CrewAI agent?

Install the framework with pip install crewai "crewaitools". Pass your Vinkius endpoint URL directly in the agent's mcps array to give them access to the expense tools.

Q: Can a CrewAI team automatically categorize Expensya transactions?

Yes, a specialized categorization agent can call listexpensecategories to get active corporate codes. It then updates uncategorized expenses using the proper corporate definitions.

Q: How do CrewAI agents collaborate on Expensya expense reports?

One agent can gather receipts and list them using listexpenses, while a second agent organizes them into folders via listexpensereports. They share state throughout the execution cycle.

Run specialized agent teams to audit, categorize, and export Expensya reports autonomously with CrewAI.

Multi-Agent Expense Auditing with CrewAI

`list_expenses` provides the raw transaction feed that your CrewAI audit agents analyze. You can assign one agent to search for policy violations and another to flag duplicate claims. Because CrewAI agents share memory, the auditing agent passes flagged items to a manager agent. The manager then uses `list_expense_reports` to file the suspicious transactions into a review folder.

Autonomous Mileage and Fleet Tracking

`list_mileage_vehicles` allows a specialized logistics agent in your CrewAI setup to manage company travel logs. The agent matches mileage claims against active vehicles to ensure submissions are accurate. This CrewAI agent works alongside a finance agent to verify the mileage rates against active vehicle lists. Together, they calculate the correct reimbursement and use `create_new_expense` to log the final claim.

Selective Tool Exposure for Secure Exports

`export_expense_data` can be restricted to specific agents using CrewAI's `MCPServerHTTP` server and custom tool filters. You can ensure only your senior accounting agent has the authority to run exports. This role-based security prevents junior research agents from accessing sensitive financial outputs. It keeps your export pipeline locked down while still allowing agents to view categories or tags.

Setup guide

Set up Expensya 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 Expensya tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

task = Task(
    description="List recent Expensya 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="Expensya Analyst",
        goal="Access and analyze Expensya data via MCP.",
        backstory="Expert analyst with direct Expensya access.",
        tools=mcp_tools,
    )

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

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