Perplexity

Collaborative financial monitoring

Assign a researcher agent to `list_transactions` while a moderator agent watches for anomalies. The crew shares memory, so they act as a single unit. This is how you scale finance without adding headcount. One agent digs into the data, and the other makes the call.

Autonomous invoice processing

Let a specialized agent iterate through `list_invoices` to identify overdue payments. The agent handles the discovery while your crew manages the next steps. You define the goal, and the agents use the tools to track down the status. It turns a manual chore into an autonomous background task.

Role-based treasury oversight

Use `get_balance` and `list_accounts` to keep your treasury team updated. You assign the tools to specific agents based on their role in the crew. This keeps your operations organized. Each agent only has access to the tools it needs to complete its part of the task.

Setup guide

Set up Mercury 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 Mercury tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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

Common questions about Mercury MCP in CrewAI

Simply pass the server URL in the agent's MCP configuration list. The crew will recognize the tools and start using them based on your instructions.

Yes. You can grant specific tools to any agent in your crew. This allows for hierarchical execution where one agent acts as the primary tool user.

The agents share context from their tool usage. If one agent fetches data via `get_account`, the entire crew can reference that info for their tasks.

Use the tool filter feature in the MCP server configuration. You decide exactly which of the eight tools each agent can call.

The data is handled in your local execution environment. Your banking tokens remain in your environment, and the MCP server ensures secure, direct communication.
