## Wikidata MCP Server
[](https://smithery.ai/server/@zzaebok/mcp-wikidata)
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
#### Installing via Smithery
To install Wikidata MCP Server for Claude Desktop automatically via [Smithery](https://smithery.ai/server/@zzaebok/mcp-wikidata):
```bash
npx -y @smithery/cli install @zzaebok/mcp-wikidata --client claude
```
#### Installing Manually
Install `uv` if it is not installed yet.
```bash
$ curl -LsSf https://astral.sh/uv/install.sh | sh
```
Then, install dependencies.
```bash
$ 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:
```bash
$ uv run src/server.py
```
If you want to test it with a simple client code (with `langchain-mcp-adapters`), run the client with:
```bash
# 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.
