Perplexity

Collaborative research and trading teams

Assign research agents to use `search_market_instruments` while your execution agents monitor for entry points. They share memory to coordinate actions. This separation allows one agent to focus on data while another handles the actual order. It mimics a professional trading desk structure.

Autonomous monitoring and response

Set up a monitor agent to watch your portfolio. If it identifies a discrepancy, it can trigger `cancel_open_order` to protect your capital. It runs 24/7, reacting to market data as it arrives. You define the rules, and the crew acts on them without human intervention.

Hierarchical order execution

Use a moderator agent to verify trades before sending them to the brokerage. It checks `get_brokerage_account` and `list_active_positions` first. Only verified orders move to `place_new_order`. This structure prevents rogue trades and ensures your risk management stays intact.

Setup guide

Set up lemon.markets 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 lemon.markets tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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

Common questions about lemon.markets MCP in CrewAI
