Chain humor into your agent logic

Plug the `get_joke` tool into your LangGraph chains to inject dynamic content into agent responses. The agent decides when to trigger a joke based on the conversation flow. This MCP server gives your chain direct access to structured humor data. You get full visibility into tool latency and input-output mapping through LangSmith tracing.

Dynamic category filtering

Use `list_joke_categories` to let your agent discover available topics before making a request. This prevents invalid calls and keeps your agent execution clean. The agent interprets the list to select appropriate categories. It then passes the chosen category to `list_jokes` to retrieve relevant content for the current context.

Batch retrieval for agent context

Call `list_jokes` to pull multiple items in a single turn. You can cache these results within your state to minimize repeat API calls during complex reasoning tasks. Your agent manages the payload from the tool output directly. It effectively handles the data as a list for conditional logic within your broader LangChain architecture.

Setup guide

Set up JokeAPI 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 JokeAPI 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({
    "jokeapi-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 JokeAPI transactions"
    })
    print(result["messages"][-1].content)

Common questions about JokeAPI MCP in LangChain

Install the necessary adapters and initialize the MCP client pointing to your Vinkius endpoint. Pass the tools directly into your agent definition to grant access to joke retrieval.

Yes, use the client session method to maintain context across multiple turns. This allows your agent to remember previous joke categories or specific user preferences.

Absolutely. You can pass safety flag arguments through the tool interface to ensure only clean jokes reach the final output.

Yes, every tool execution is fully observable. You can monitor latency and token usage inside your existing tracing environment.

The server only touches public joke data. No user conversational history is stored or processed on the server side, ensuring your data remains isolated.
