How to Use the Pennylane MCP in CrewAI

Q: How do I load the Pennylane MCP Server tools into a CrewAI agent?

You pass your Vinkius endpoint URL directly into the mcps list of your Agent definition. CrewAI automatically discovers the tools, making them available for your accounting agents.

Q: Can I restrict which Pennylane MCP tools a CrewAI agent can use?

Yes, you use MCPServerHTTP with a toolfilter to expose only specific tools. For example, you can allow a billing agent to use createcustomer while blocking it from accessing supplier invoices.

Q: How do CrewAI agents handle French tax code categorization?

Your agents query listcategories to understand your French chart of accounts. They use this context to map products and customers to the correct accounting codes during automated runs.

Run a multi-agent team to manage Pennylane invoices and customer records autonomously using CrewAI.

Autonomous Supplier Auditing Teams

`list_suppliers` allows your CrewAI research agent to compile a directory of active French vendors. A second analyst agent then cross-references this list against outstanding expenses to find missing paperwork. The analyst agent calls `get_supplier_details` to verify VAT IDs on the fly. This cooperative multi-agent execution turns a multi-day auditing chore into a background task that runs entirely without human intervention.

Automated Quote-to-Invoice Pipelines

`list_estimates` feeds pending French sales quotes to a monitoring agent in your CrewAI setup. When a quote is marked as accepted, a billing agent takes over to initiate the onboarding process. The billing agent uses `create_customer` to register the client and then generates the initial invoice. By dividing the work across specialized agents, your team avoids race conditions and keeps your Pennylane ledger clean.

CrewAI Accounting Ledger Synchronization

`list_customer_invoices` pulls all historical French receivables into your CrewAI shared memory pool. Your specialized agent team uses this data to track outstanding payments and draft follow-up notices. If a customer disputes a charge, the agent calls `get_customer_invoice_details` to check individual line items. This MCP Server integration allows your agents to act as autonomous account managers, keeping your books accurate.

Setup guide

Set up Pennylane 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 Pennylane tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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

Common questions about Pennylane MCP in CrewAI

You pass your Vinkius endpoint URL directly into the `mcps` list of your Agent definition. CrewAI automatically discovers the tools, making them available for your accounting agents.

Yes, you can set up a manager agent to oversee worker agents handling `list_estimates` and `get_estimate_details`. The manager checks the output before letting any updates hit your ledger.

Yes, you use `MCPServerHTTP` with a `tool_filter` to expose only specific tools. For example, you can allow a billing agent to use `create_customer` while blocking it from accessing supplier invoices.

Your agents query `list_categories` to understand your French chart of accounts. They use this context to map products and customers to the correct accounting codes during automated runs.

Your customer records, estimates, and tax invoices are handled within ephemeral V8 sandboxes. CrewAI agents process the data locally or via secure HTTP/stdio transports, meaning your French accounting data is never cached or stored on Vinkius servers.
