+= About Model Context Protocol (MCP) server 
+
+A Model Context Protocol (MCP) server is a program that implements the Model Context Protocol. The protocol creates a secure intermediary between a large language model (LLM) and external resources, such as data sources or software applications. Using the protocol, an MCP server provides a standardized way for an LLM to increase context by requesting and receiving real-time updates from external resources. This functionality transforms the LLM from a static knowledge base into a dynamic system that uses real-time information to answer questions or complete actions.
+
+:FeatureName: MCP server
+include::snippets/technology-preview.adoc[]
+
+MCP server is disabled by default. To enable the functionality, add the `spec.featureGate.MCPServer` specification to the `OLSConfig` custom resource (CR).

+= Enabling MCP server
+
+Enable the Model Context Protocol (MCP) server so that a large language model (LLM) can securely access an external tool, such as a database or API, and obtain real-time updates.
+
+.Prerequisites
+
+* You have installed the the {ols-long} Operator.
+
+* You have configured a large language model provider.
+
+* You have deployed the {ols-long} service.
+
+.Procedure
+
+. Open the {ols-long} `OLSconfig` custom resource (CR) file by running the following command:
++
+[source,terminal]
+----
+$ oc edit olsconfig cluster
+----
+
+. Modify the `spec.ols.featureGates` specification to include MCP server information.
++
+[source,yaml]
+----

+<1> Specifies the MCPServer functionality.
+<2> Specifies the name of the MCP server.
+<3> Specifies the URL path that the MCP server uses to communicate.
+<4> Specifies the time that the MCP server has to respond to a query. If the client does not receive a query within the time specified, the MCP server times out. In this example, the timeout is 30 seconds.
+<5> Specifies the amount of time a client waits for new data from a Server-Sent Events (SSE) connection. If the client does not receive data within that time, the client closes the connection.
+<6> When you set `enableSSE` to true the MCP server establishes a one-way channel that the MCP server uses to push updates to the client whenever the server has new information. The default setting is `false`. 
+
+. Click *Save*. 
++
+The save operation saves the file and applies the changes so that the MCP server is available to the {ols-long} service.
