## MCP Server
### Public Vespa MCP server
We don't provide any official [MCP](https://modelcontextprotocol.io/) server at this time, but will update this page as soon as we do.

### Personal MCP server
Users can enable MCP server capablities in their own Vespa apps.
This can be done by adding `McpRequestHandler` to `services.xml` with one or more `McpSpecProvider` components.

A pre-built `McpSearchSpecProvider` already exists, and a usage example can be found in [this sample app](https://github.com/vespa-engine/sample-apps/tree/master/examples/mcp-server-app).
This exposes Vespa search to LLMs via the `/mcp/` endpoint.

Users can add more tools by implementing `McpSpecProvider` and adding the components in `services.xml`.

#### Example MCP config
Add this to `services.xml`
```xml
<component id="com.yahoo.search.mcp.McpSearchSpecProvider" bundle="container-search-and-docproc"/>
<handler id="ai.vespa.mcp.McpRequestHandler" bundle="container-disc">
<binding>http://*/mcp/*</binding>
</handler>
```
