How to Use the Guru MCP in LangChain

Q: How do I search Guru from a LangChain agent?

You pass the searchknowledgebase tool to your agent's toolset. The agent decides when to call it based on your prompt instructions.

Q: Is the Guru MCP Server connection stable?

You check the connection status using the verifyapiconnection tool. It returns a success status if your credentials are valid and the API is reachable.

Connect Guru to your LangChain agents to turn internal documentation into actionable steps within your reasoning pipelines.

Perplexity

Chain knowledge retrieval in LangChain

Your agent uses `search_knowledge_base` to grab relevant context before executing downstream tasks. It feeds the results directly into your next chain link. This keeps your LLM grounded in current documentation. You avoid the guesswork that ruins automated workflows.

Manage Guru cards from LangChain

Update your wiki dynamically using `update_knowledge_card` as your agent finishes a project. It reflects changes in real-time without you lifting a finger. Use `create_knowledge_card` to log findings from your chain execution. Your team stays updated automatically.

Verify MCP Server health in chains

Run `verify_api_connection` as a pre-flight check in your agent setup. It confirms your Guru connection is live before the chain fires. If the connection fails, your agent skips the knowledge step. This prevents expensive failures during complex reasoning tasks.

Setup guide

Set up Guru MCP in LangChain

Prerequisites

Python 3.10+ installed
langchain-mcp-adapters + langgraph packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install langchain-mcp-adapters langgraph langchain-openai. The MCP adapters package converts MCP tools into native LangChain BaseTool objects.
2

Connect via HTTP transport
Use MultiServerMCPClient with "transport": "http" pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create a ReAct agent
Pass the discovered tools to create_react_agent() from LangGraph. The agent automatically routes Guru tool calls through the MCP protocol.
4

Run with any LLM
Swap ChatOpenAI for ChatAnthropic, ChatGoogleGenerativeAI, or any LangChain-compatible model. The MCP tools work identically across all providers.

agent.py

from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain_openai import ChatOpenAI

async with MultiServerMCPClient({
    "guru-mcp": {
        "transport": "http",
        "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp",
    }
}) as client:
    tools = client.get_tools()

    agent = create_react_agent(
        ChatOpenAI(model="gpt-4o"),
        tools,
    )
    result = await agent.ainvoke({
        "messages": "List recent Guru transactions"
    })
    print(result["messages"][-1].content)
