How to Use the N-Gram Frequency Engine MCP in AutoGen

Q: How do I integrate the N-Gram Frequency Engine into AutoGen?

Install autogen-extmcp. Use mcpservertools with StreamableHttpServerParams pointing to your endpoint. Pass the resulting tool list into your AssistantAgent constructor.

Q: Does the N-Gram Frequency Engine support AutoGen's streaming transport?

Yes. The McpToolAdapter handles the schema conversion automatically. Your agents can trigger the extraction over Streamable HTTP without any custom networking code.

Give your AutoGen agents the exact phrase frequencies they need to debate document analysis.

Ground Agent Debates in Hard Math

The `extract_ngram_frequencies` tool gives your AutoGen agents a factual baseline for their conversations. When a summarization agent claims a document focuses on a specific topic, a critical agent calls this tool to verify the exact bigram counts. The math settles the argument immediately. Instead of two LLMs hallucinating competing interpretations, they both look at the deterministic JSON frequency map and converge on a reality-based consensus.

Token Optimization for AutoGen

`extract_ngram_frequencies` saves your AutoGen deployment massive amounts of context space. Multi-agent systems burn tokens rapidly when passing full documents back and forth. You route the raw text through this MCP Server first. The agents then debate over the condensed unigram and trigram dictionaries, cutting your API costs while maintaining perfect analytical accuracy.

Specialized Analytical Roles

The `extract_ngram_frequencies` tool allows you to create a dedicated quantitative linguist agent. You assign the tool exclusively to this agent, forcing the rest of the swarm to request exact phrase counts from the specialist. This mimics real-world data science teams. The creative agents generate hypotheses about the text, and the specialist agent runs the deterministic extraction to prove or disprove those theories with hard numbers.

Setup guide

Set up N-Gram Frequency Engine 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 N-Gram Frequency Engine 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="N-Gram Frequency Engine_assistant",
    model_client=OpenAIChatCompletionClient(model="gpt-4o"),
    tools=tools,
)

result = await agent.run("List recent N-Gram Frequency Engine 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="N-Gram Frequency Engine_assistant",
        model_client=OpenAIChatCompletionClient(model="gpt-4o"),
        workbench=workbench,
    )

    result = await agent.run("List recent N-Gram Frequency Engine data")
    print(result.messages[-1].content)

Common questions about N-Gram Frequency Engine MCP in AutoGen

Install `autogen-ext[mcp]`. Use `mcp_server_tools` with `StreamableHttpServerParams` pointing to your endpoint. Pass the resulting tool list into your `AssistantAgent` constructor.

Assign it to a specialized data analysis agent. When other agents in the chat need to know how often a specific phrase occurs, they prompt the specialist to run the extraction.

Yes. The `McpToolAdapter` handles the schema conversion automatically. Your agents can trigger the extraction over Streamable HTTP without any custom networking code.

Writing and executing unverified code introduces failure points and takes multiple conversation turns. This MCP Server provides an instant, pre-tested, high-performance counting mechanism in a single tool call.

The server only receives the specific text strings your agent chooses to send it. Vinkius runs the extraction inside a zero-trust sandbox. The process maps the N-grams, returns the data, and terminates without logging your proprietary text.
