How to Use the lemon.markets MCP in AutoGen

Q: How do I register lemon.markets tools with AutoGen agents?

Use pip install -U "autogen-extmcp" to install the extension. Connect via mcpservertools using the Vinkius URL, and pass the resulting tools list to your AssistantAgent.

Q: Can AutoGen agents debate before activating a lemon.markets order?

Yes. You can configure one agent to create the order with placeneworder and require a second risk-checking agent to call activatependingorder only after verifying account limits.

Q: How do AutoGen agents handle European stock searches on lemon.markets?

An agent can call searchmarketinstruments to find specific ISINs. It then shares the instrument details in the group chat, allowing other agents to analyze the asset before executing a trade.

Q: What happens if an AutoGen agent tries to execute a trade during a rate limit block?

The tool call to getlatestquote or placeneworder will return an error. Your conversational agents can detect this failure and agree to pause trading until the rate limit resets.

Perplexity

Multi-agent consensus for lemon.markets order execution

Let your agents argue before spending your capital. In AutoGen, a trading agent can propose a trade using `place_new_order`, but a separate risk-management agent must verify the trade against `get_brokerage_account` before execution. Only when both agents agree does the system call `activate_pending_order`. This debate prevents hasty executions and keeps your algorithmic trading aligned with your risk tolerances.

Coordinate portfolio rebalancing using AutoGen agents

Set up a conversation where one agent monitors your portfolio via `list_active_positions` while another checks market prices. They negotiate the exact volume of shares to buy or sell based on real-time data. If a trade proposal is rejected due to high volatility, the agents can coordinate to call `cancel_open_order` and wait for a better entry point. This cooperative logic runs entirely within the AutoGen conversation loop.

Resolve execution conflicts with an MCP Server

When market conditions shift rapidly, single-agent systems often fail. Using this MCP Server, your AutoGen agents share access to `get_latest_quote` and `list_brokerage_orders` to resolve execution conflicts in real time. If one agent detects a stale quote, it flags the issue to the executing agent. They work together to adjust the order parameters before finalizing the transaction, keeping your capital safe.

Setup guide

Set up lemon.markets MCP in AutoGen

Prerequisites

Python 3.10+ installed
autogen-ext[mcp] package
Active Vinkius subscription with a valid endpoint token

1

Install AutoGen with MCP
Run pip install "autogen-ext[mcp]" autogen-agentchat. The MCP extension includes mcp_server_tools for stateless tool access.
2

Fetch tools from the MCP
Call mcp_server_tools(SseServerParams(url=...)) with your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Run your agent
Pass the tools to AssistantAgent and call agent.run(). The agent invokes lemon.markets tools and returns structured results.

agent.py

from autogen_ext.tools.mcp import SseServerParams, mcp_server_tools
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient

server_params = SseServerParams(
    url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)

tools = await mcp_server_tools(server_params)

agent = AssistantAgent(
    name="lemon.markets_assistant",
    model_client=OpenAIChatCompletionClient(model="gpt-4o"),
    tools=tools,
)

result = await agent.run("List recent lemon.markets data")
print(result.messages[-1].content)

Prerequisites

Python 3.10+ installed
autogen-ext[mcp] + autogen-agentchat
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Same packages as above. McpWorkbench is ideal when your agent needs stateful sessions across multiple tool calls.
2

Use McpWorkbench as context manager
Wrap your agent in async with McpWorkbench(...) to maintain shared state and resources. The workbench manages the full MCP session lifecycle.
3

Run with workbench
Pass workbench=workbench to your agent. State is preserved across multiple tool calls within the same session.

agent.py

from autogen_ext.tools.mcp import McpWorkbench, SseServerParams
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient

server_params = SseServerParams(
    url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)

async with McpWorkbench(server_params) as workbench:
    agent = AssistantAgent(
        name="lemon.markets_assistant",
        model_client=OpenAIChatCompletionClient(model="gpt-4o"),
        workbench=workbench,
    )

    result = await agent.run("List recent lemon.markets data")
    print(result.messages[-1].content)
