How to Use the Lexzur MCP in Google ADK

Q: Can I restrict which Lexzur tools are exposed to my Google ADK agent?

Yes, you can use the optional toolnames filter when initializing McpToolset. This lets you restrict access to sensitive tools like listinvoices while keeping others open.

Q: Can Gemini analyze attorney time logs using this server?

Yes, the agent calls listtimelogs to retrieve billable hours. Gemini's reasoning engine can then analyze these logs to detect inefficiencies in corporate legal spending.

Run enterprise legal operations by connecting Google ADK agents directly to your Lexzur workspace.

Perplexity

Query legal files with Google ADK

The `list_documents` tool exposes your entire Lexzur file repository to Gemini models running on the Google ADK. This lets your agent scan thousands of legal pages using Gemini's million-token context window. By combining this with `get_matter`, your agent extracts key clauses from old cases to draft new filings. This workflow bypasses manual search, pulling exact data from your cloud storage.

Sync corporate contacts via Google ADK

This Lexzur MCP Server exposes `list_contacts` and `list_companies` to keep your enterprise CRM aligned with your legal database. Google ADK agents pull this contact data and pipe it into BigQuery for analysis. Your agent can then cross-reference client lists with active corporate structures. This eliminates manual data syncing between your sales pipeline and your legal department.

Monitor litigation pipelines in real time

The `list_litigation` tool lets your Google ADK agent track active court dates and trial schedules. The agent monitors these cases and updates your internal dashboards on Google Cloud. Using `list_tasks`, the agent assigns follow-ups to specific attorneys based on court updates. This ensures your legal ops team responds to court motions within hours, not days.

Setup guide

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