How to Use the Justia Legal Intelligence MCP in LlamaIndex

Q: How do I install Justia Legal Intelligence for LlamaIndex?

Run pip install llama-index-tools-mcp and set up a BasicMCPClient. Wrap it with McpToolSpec and pass the async tool list to your FunctionAgent.

Q: How do I filter which legal tools the agent can use?

Use the allowedtools parameter when initializing the agent. You restrict it to only pull statutes if you want to prevent it from searching case law.

Turn live case law into a searchable vector index by connecting Justia Legal Intelligence to your LlamaIndex RAG applications.

Perplexity

Vectorize Live Statutory Text

When you call `get_state_statutes`, LlamaIndex ingests the raw legislative text and embeds it directly into your vector store. You aren't just reading a law. You build a permanent, queryable knowledge base of state codes. Your agent runs semantic searches against that indexed law to find specific procedural rules or penalties. This grounds the AI's answers in actual, current legislation rather than outdated training weights.

Ground RAG Apps with this MCP Server

Executing `search_legal_cases` pulls down case summaries and holdings that LlamaIndex instantly chunks and indexes. You ask your agent a question, and it retrieves the exact judicial precedent from its newly built vector database. This eliminates legal hallucinations. The agent synthesizes its response using only the court decisions you just fetched, providing exact citations and docket references for every claim it makes.

Build Unified Legal Knowledge Bases

You combine `search_legal_cases` with your own internal document stores to cross-reference firm memos with live Justia data. The agent reads your draft brief, searches for the cited cases, and verifies the holdings. If a case was overturned or modified, the indexed Justia data flags the discrepancy. Your RAG pipeline acts as an automated cite-checker that actually reads the law.

Set up Justia Legal Intelligence MCP in LlamaIndex

Prerequisites

Python 3.10+ installed
llama-index-tools-mcp package
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install llama-index-tools-mcp llama-index-llms-openai. The MCP tools package provides BasicMCPClient and McpToolSpec.
2

Connect with BasicMCPClient
Point BasicMCPClient to your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports SSE and Streamable HTTP transports.
3

Convert to LlamaIndex tools
Call mcp_tool_spec.to_tool_list_async() to convert all Justia Legal Intelligence MCP tools into native FunctionTool objects that any LlamaIndex agent can use.
4

Run with any LLM
Create a FunctionAgent with the tools and your preferred LLM. Swap OpenAI for Anthropic, Gemini, or any LlamaIndex-supported provider.

agent.py

from llama_index.tools.mcp import BasicMCPClient, McpToolSpec
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

# Connect to the MCP
mcp_client = BasicMCPClient(
    "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)
mcp_tool_spec = McpToolSpec(client=mcp_client)

# Convert MCP tools to LlamaIndex tools
tools = await mcp_tool_spec.to_tool_list_async()

# Create and run the agent
agent = FunctionAgent(
    tools=tools,
    llm=OpenAI(model="gpt-4o"),
    system_prompt="You have access to Justia Legal Intelligence tools.",
)
response = await agent.run("List recent Justia Legal Intelligence data")

Common questions about Justia Legal Intelligence MCP in LlamaIndex

Run `pip install llama-index-tools-mcp` and set up a `BasicMCPClient`. Wrap it with `McpToolSpec` and pass the async tool list to your `FunctionAgent`.

Yes. The framework takes the returned case summaries and embeds them into your active index. You run semantic queries against that specific set of cases later.

It works perfectly with standard tool calling. You feed the returned legal text directly into your document parser for immediate indexing.

Use the `allowed_tools` parameter when initializing the agent. You restrict it to only pull statutes if you want to prevent it from searching case law.

The MCP Server only sees the legal keywords and state names you search for. Vinkius routes these requests through a zero-trust architecture. No search parameters or retrieved case files are logged on the server after the execution finishes.
