Provides tools for searching Wikipedia and retrieving page content, enabling AI agents to access Wikipedia knowledge.
This server does not currently have a deployable release on Glama. Follow the repository's setup instructions to install and configure it for your MCP client, including any required credentials and local dependencies.
An AI-powered Wikipedia research agent demonstrating how FastAPI, FastMCP, LangChain, and LangGraph can work together to build a modular tool-using AI application.
The project exposes Wikipedia capabilities through an MCP (Model Context Protocol) server and allows a LangChain/LangGraph agent to automatically discover and use those tools.

The FastMCP server exposes two tools.
search_wikipediaSearches Wikipedia for a given topic.
@mcp.tool
def search_wikipedia(query: str):
...Example:
Search Wikipedia for Albert EinsteinThe agent can automatically decide to call:
search_wikipedia("Albert Einstein")get_wikipedia_pageRetrieves the content of a specific Wikipedia page.
@mcp.tool
def get_wikipedia_page(title: str):
...Example:
Get the Wikipedia page for Artificial IntelligenceThe agent can call:
get_wikipedia_page("Artificial Intelligence")The MCP server runs using:
mcp.run(transport="stdio")The LangChain client connects to the MCP server:
client = MultiServerMCPClient(
{
"wikipedia": {
"command": "python",
"args": ["server.py"],
"transport": "stdio",
}
}
)The client then discovers the available MCP tools:
tools = await client.get_tools()These tools are passed to the LangGraph agent:
agent = create_react_agent(
model,
tools
)The LLM can then decide which tool to use based on the user's request.
git clone https://github.com/YOUR_USERNAME/langchain-mcp-wikipedia.gitcd langchain-mcp-wikipediaWindows:

MCP provides a standardized way to expose capabilities as tools.
