How to Use the Deterministic Readability Scorer MCP in Google ADK

Q: How do I integrate the Deterministic Readability Scorer with my Google ADK agent?

You'll wrap the server URL in an McpToolset instance. Then you pass that toolset into the tools list when creating your LlmAgent. The ADK handles the rest.

Run deterministic readability analysis on your BigQuery data using Google ADK and Gemini's long-context power.

Analyze Text from BigQuery

Your data is already in Google Cloud, so keep your analysis there too. Pipe text directly from BigQuery to an agent built with the Google ADK. It can then use `calculate_flesch_kincaid` from this MCP server to score document readability at scale. Imagine an agent that monitors a table of user-generated content. It can automatically run `calculate_gunning_fog` on new entries and flag complex posts for review, all within your existing GCP project.

Consistent Metrics for Google ADK Agents

When your agent needs to decide if a text is too complex, a guess isn't good enough. This MCP server provides tools like `calculate_flesch_kincaid` that return a hard number. It’s based on classic linguistic formulas, not a model's whim. This is especially useful with Gemini's long-context window. Your agent can analyze massive documents, pull out sections, and get consistent readability scores for each part. The ADK makes it easy to filter which tools your agent can access, giving you fine-grained control.

Estimate Content Effort

Use the `calculate_reading_time` tool to get a solid estimate of how long content will take to read. You feed it text, and it returns the time based on a standard 200 WPM, which you can override. An agent could use this to automatically prioritize a reading list from Google Cloud Storage or tag documents in a CMS with estimated read times. It’s a simple, practical tool for managing content workflows within the Google ecosystem.

Setup guide

Set up Deterministic Readability Scorer MCP in Google ADK

Prerequisites

Python 3.10+ installed
google-adk package (pip install google-adk)
Active Vinkius subscription with a valid endpoint token

1

Install Google ADK

Run pip install google-adk to install the Agent Development Kit. MCP support is included via the McpToolset class.
2

Connect via SSE transport

Use McpToolset.from_server() with SseServerParams pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create an LlmAgent

Pass the returned mcp_tools list directly to LlmAgent(tools=mcp_tools). The ADK maps each MCP tool to a native Gemini function call — no manual schema definitions required.
4

Run with any Gemini model

The agent works with any Gemini model (gemini-2.0-flash, gemini-2.5-pro, etc.). Copy the full example on the right to get started with Deterministic Readability Scorer tools in your ADK agent.

agent.py

from google.adk.agents import LlmAgent
from google.adk.tools.mcp_tool.mcp_toolset import McpToolset
from google.adk.tools.mcp_tool.mcp_session_manager import SseServerParams

# Connect to the MCP via SSE
mcp_tools, exit_stack = await McpToolset.from_server(
    connection_params=SseServerParams(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    )
)

# Create your agent with auto-discovered tools
agent = LlmAgent(
    name="Deterministic Readability Scorer_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Deterministic Readability Scorer tools via MCP.",
    tools=mcp_tools,
)

Common questions about Deterministic Readability Scorer MCP in Google ADK

You'll wrap the server URL in an `McpToolset` instance. Then you pass that toolset into the `tools` list when creating your `LlmAgent`. The ADK handles the rest.

Yes, that's a perfect use case. Your Google ADK agent can fetch text from BigQuery or Cloud Storage, then pass it to the `calculate_gunning_fog` tool to get a score.

The tools themselves process text chunks you send them. Your agent can manage the long context, breaking down a large document and sending relevant sections to `calculate_flesch_kincaid` for scoring piece by piece.

LLMs are bad at the precise math required for these formulas. You'll get an approximation at best, and it won't be repeatable. This MCP server does the actual calculation for a guaranteed, deterministic result.

Your text data is processed in-memory and never written to disk. The Vinkius platform uses zero-trust, ephemeral containers for each request. Once the score is calculated from the text string, the container and all its data are destroyed.
