How to Use the Legal Counsel Prover MCP in Google ADK

Q: What happens if the agent fails the Legal Counsel Prover checks in Google ADK?

The validatelegalanalysis tool returns a structured error payload detailing the missing elements, such as an unaddressed contrary precedent or a missing docket number. The agent must rewrite the analysis to address these gaps before it can finalize the task.

Q: Can I restrict which tools this MCP Server exposes to my agent?

Yes, you can use the toolnames filter in the Google ADK toolset configuration. This limits your agent's access to only the specific legal validation functions required for your workflow.

Perplexity

Ground long-context legal briefs in BigQuery data

The `validate_legal_analysis` tool binds your agent's long-context reasoning to the specific facts stored in your Google Cloud databases. It pulls raw client records, dates, and evidence from BigQuery and forces the agent to map them directly to cited statutes. This keeps Gemini from drifting into generic legal essays. It doesn't let the agent slide on vague generalizations; the MCP Server demands a tight connection between your actual case evidence and the legal claims, rejecting any analysis that fails this test.

Validate procedural deadlines inside Google ADK

The `validate_legal_analysis` tool enforces strict procedural timelines and filing requirements for every litigation motion your agent drafts. It checks the target court rules against the dates in your case file to ensure no statutory deadlines are missed. But here is the catch: you cannot rely on the LLM to guess the dates. This MCP toolset keeps your enterprise legal workflows compliant without requiring manual calendar audits for every draft.

Force objective evaluation of adverse legal arguments

The `validate_legal_analysis` tool requires your agent to identify and analyze contrary precedents and opposing arguments before delivering a final memo. It stops Gemini from writing one-sided arguments that collapse under scrutiny in court. By forcing the agent to document adverse positions, you get a realistic view of litigation risks. The tool validates that the agent has addressed these weaknesses, ensuring your strategy is battle-tested. Cut the fluff and verify.

Setup guide

Set up Legal Counsel Prover 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 Legal Counsel Prover tools in your ADK agent.

# 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"
    )
