How to Use the Harmonic MCP in AutoGen

Q: How do I equip AutoGen agents with Harmonic?

Install the extension via pip install -U "autogen-extmcp". Use mcpservertools to fetch the endpoints, and McpToolAdapter will automatically format them for your agents. Point it at this MCP Server URL.

Let AutoGen agents debate startup metrics and funding histories using live Harmonic data.

Perplexity

Multi-agent due diligence debates

Harmonic feeds raw startup data into AutoGen debate structures. The skeptical agent calls `get_company_stats` to look for stagnating headcount. The defending agent counters by pulling recent press releases with `list_company_news`. They argue over the actual data retrieved from the API, eventually reaching a consensus based on hard metrics.

Automated startup sourcing workflows

Harmonic automates daily deal sourcing. A dedicated sourcing agent runs `search_startups` every morning using strict industry and location filters. It passes the raw list to a secondary analyst agent. That agent uses `enrich_company` to gather firmographics and `list_funding_rounds` to filter out companies that just raised. You only see the final, curated list.

Harmonic MCP Server founder checks

Harmonic verifies executive backgrounds automatically. Your research agent uses `enrich_person` to pull professional histories and social signals for every executive. If the data seems thin, a verification agent double-checks the company's momentum via `list_traction_signals`. The multi-agent conversation catches red flags before you send an email.

Setup guide

Set up Harmonic 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 Harmonic 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="Harmonic_assistant",
    model_client=OpenAIChatCompletionClient(model="gpt-4o"),
    tools=tools,
)

result = await agent.run("List recent Harmonic 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="Harmonic_assistant",
        model_client=OpenAIChatCompletionClient(model="gpt-4o"),
        workbench=workbench,
    )

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

Common questions about Harmonic MCP in AutoGen

Install the extension via `pip install -U "autogen-ext[mcp]"`. Use `mcp_server_tools` to fetch the endpoints, and `McpToolAdapter` will automatically format them for your agents. Point it at this MCP Server URL.

Yes. You pass the tool list to any agent in your group chat. They can all call the API independently during their conversation.

The agents read the tool schemas natively. They know exactly which parameters to pass for headcount limits, locations, and industry tags.

The agent receives an error message directly from the MCP integration. It can then pause, retry, or ask another agent for help.

Harmonic handles founder histories and investment thesis data. AutoGen agents process this information locally during their debates. The MCP connection runs in an ephemeral V8 isolate, keeping your firm's sourcing strategy private.
