Map book editions using Google ADK

This MCP Server uses `thing_isbn` to help your Google ADK agent map paperback, hardcover, and audiobook editions. The agent can then pipe these resolved LibraryThing ISBN lists directly into BigQuery for enterprise storage. The integration uses the standard streamable HTTP parameters to expose LibraryThing tools to Gemini. Because Gemini handles massive context windows, your Google ADK agent can feed a long list of raw ISBNs into the prompt and let the model resolve them all in one go.

Score catalog depth with this MCP Server

By calling `get_book_coverage`, your Google ADK agent checks how thoroughly a book is indexed on LibraryThing. Your Python agent uses this 0-to-1 score to decide whether to trust the metadata or seek alternative sources. You can configure the MCP toolset to expose only this tool to your Google ADK agent. This keeps your Gemini model focused and prevents it from wasting tokens on unrelated LibraryThing metadata queries.

Pull LibraryThing work data via Google ADK

The `get_work` and `what_work` tools let your Google ADK agent find a book's work ID and retrieve its full catalog details. First, the agent runs `what_work` to find the ID, then it pulls the LibraryThing author and review counts into Gemini. Since the Google ADK integrates with Vertex AI, you can use these tools to build automated library research agents. These agents can analyze LibraryThing reader reviews and catalog trends without manual coding.

Setup guide

Set up LibraryThing 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 LibraryThing 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="LibraryThing_agent",
    model="gemini-2.0-flash",
    instruction="You have access to LibraryThing tools via MCP.",
    tools=mcp_tools,
)

Common questions about LibraryThing MCP in Google ADK

You install the package and initialize the toolset using the LibraryThing server parameters. Then, pass that toolset directly to your Google ADK LlmAgent constructor so Gemini can access the book tools.

Yes, you can use the optional tool names filter in the Google ADK toolset configuration. This lets you expose only `get_book_coverage` while hiding the other LibraryThing endpoints from Gemini.

Yes, the Google ADK toolset supports both stdio and HTTP transports for the LibraryThing server. You can run the server locally or host it on Google Cloud Run depending on your architecture.

Your Google ADK agent will receive an empty or null result from `what_work`. You should write a prompt instruction telling Gemini to stop or ask for a different LibraryThing book if this happens.

The server handles only public book metadata and ISBN strings. All Google ADK traffic is routed through ephemeral sandbox environments, meaning your LibraryThing search queries are never cached or stored on external servers.
