The link:https://modelcontextprotocol.io/docs/getting-started/intro[Model Context Protocol (MCP)] is an open standard that enables AI applications to access real-time information from external sources. The Liberty MCP Server feature `mcpServer-1.0` allows developers to expose the business logic of their applications, allowing it to be integrated into agentic AI workflows.

This beta release of Liberty includes important updates to the `mcpServer-1.0` feature including configurable endpoint paths and notable bug fixes.

=== Prerequisites
To use the `mcpServer-1.0` feature, it is required to have `Java 17`` or later installed on your system.

=== Configure custom MCP endpoint paths (Currently under review as this is not working as intended after testing with multiple modules)
=== Configure custom MCP endpoint paths (Currently disabled pending review - testing revealed inconsistent behavior across multiple modules)

Previously, the MCP endpoint was hard-coded to `/mcp` under the web application context root. You can now configure custom endpoint paths to better suit your application architecture and naming conventions.

==== 3) Fixed encoder bean isolation in multi-application deployments

Previously, encoder beans from multiple applications were stored in a static list within `McpCdiExtension`, causing beans from different applications to interfere with each other. This behaviour could result in encoder beans from one application being incorrectly called in another application, unpredictable behavior in multi-application deployments, and potential security issues with cross-application bean access.

This has been fixed to ensure proper isolation of encoder beans per application, preventing cross-application interference and ensuring each application uses only its own encoder beans.
