Wikidata MCP Server
A server implementation for Wikidata API using the Model Context Protocol (MCP). This project provides tools to interact with Wikidata, such as searching identifiers (entity and property), extracting metadata (label and description) and executing sparql query.
Installation
Install uv if it is not installed yet.
$ curl -LsSf https://astral.sh/uv/install.sh | sh
Then, install dependencies.
$ git clone https://github.com/zzaebok/mcp-wikidata.git
$ cd mcp-wikidata
$ uv sync
# if you want to run client example together
$ uv sync --extra example
Run
Run the server with:
$ uv run src/server.py
If you want to test it with a simple client code (with langchain-mcp-adapters), run the client with:
# in another shell
$ uv run src/client.py
The LLM extracts valid entity and property identifiers, executes a sparql query, and finally recommend a movie directed by Bong Joon-ho.
