How to Use the Modulr MCP in CrewAI

Q: How do CrewAI agents handle rate limits when querying Modulr?

If multiple agents call modulrlistpayments simultaneously, the managed MCP Server queues the requests to avoid rate limits. CrewAI's internal retry mechanisms will also pause and retry the tool execution if the API returns a busy status.

Q: Does this setup support both GBP and EUR virtual accounts?

Yes, your agents can specify the currency when calling modulrcreateaccount. The server handles the underlying banking rules for both UK and European financial networks.

Run autonomous multi-agent financial operations using CrewAI and the Modulr MCP Server.

Perplexity

Multi-agent reconciliation and execution

Divide and conquer your back-office tasks. You can set up a CrewAI team where a reconciliation agent monitors ledger histories with `modulr_get_transactions` while a payout agent executes batch transfers using `modulr_create_payment`. The agents share context and memory. If the auditor agent spots a discrepancy, it instructs the payout agent to hold off on running `modulr_list_payments` until the ledger matches.

Automated vendor onboarding with CrewAI

Let specialized agents handle partner setup. A compliance agent can inspect new profiles with `modulr_get_customers`, while a setup agent registers their bank details using `modulr_create_beneficiary`. This multi-agent setup ensures that no beneficiary is mapped until the customer profile is fully validated. The CrewAI framework manages the handoffs, passing data between the tools without friction.

Autonomous ledger management with CrewAI

Manage complex virtual account structures without manual intervention. Your agent crew can monitor incoming volumes and dynamically spin up new EUR or GBP wallets using `modulr_create_account` when specific thresholds are met. By exposing the Modulr MCP Server to your crew, you enable autonomous liquidity routing. The agents track live balances across your setup using `modulr_get_accounts` and rebalance funds as needed.

Setup guide

Set up Modulr 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 Modulr tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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

Common questions about Modulr MCP in CrewAI

You can pass the Vinkius endpoint URL directly into the agent's setup array. This instantly exposes tools like `modulr_create_payment` and `modulr_create_account` to that specific agent's toolkit.

Yes, you can use a tool filter during registration. This lets you give your auditor agent access to `modulr_get_transactions` while restricting `modulr_create_payment` strictly to your executive agent.

If multiple agents call `modulr_list_payments` simultaneously, the managed MCP Server queues the requests to avoid rate limits. CrewAI's internal retry mechanisms will also pause and retry the tool execution if the API returns a busy status.

Yes, your agents can specify the currency when calling `modulr_create_account`. The server handles the underlying banking rules for both UK and European financial networks.

Absolutely. All bank account numbers, payee details, and ledger balances are processed within Vinkius's ephemeral sandboxes. CrewAI only sees the text outputs returned by tools like `modulr_get_accounts` during active tasks.
