+# MCP Kotlin Server Sample
+
+A sample implementation of an MCP (Model Communication Protocol) server in Kotlin that demonstrates different server configurations and transport methods.
+
+## Features
+
+- Multiple server operation modes:
+ - Standard I/O server
+ - SSE (Server-Sent Events) server with plain configuration
+ - SSE server using Ktor plugin
+- Built-in capabilities for:
+ - Prompts management
+ - Resources handling
+ - Tools integration
+
+## Getting Started
+
+### Running the Server
+
+To run the server in SSE mode on the port 3001, run:
+
+```bash
+./gradlew run
+```
+
+### Connecting to the Server
+
+For SSE servers (both plain and Ktor plugin versions):
+1. Start the server
+2. Use the MCP inspector to connect to `http://localhost:/sse`
+
+## Server Capabilities
+
+- **Prompts**: Supports prompt management with list change notifications
+- **Resources**: Includes subscription support and list change notifications
+- **Tools**: Supports tool management with list change notifications
+
+## Implementation Details
+
+The server is implemented using:
+- Ktor for HTTP server functionality
+- Kotlin coroutines for asynchronous operations
+- SSE for real-time communication
+- Standard I/O for command-line interface

+# Gradle start up script for POSIX generated by Gradle.
+#
+# Important for running:
+#
+# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+# noncompliant, but you have some other compliant shell such as ksh or
+# bash, then to run this script, type that shell name before the whole
+# command line, like:
+#
+# ksh Gradle
+#
+# Busybox and similar reduced shells will NOT work, because this script
+# requires all of these POSIX shell features:
+# * functions;
+# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+# * compound commands having a testable exit status, especially «case»;
+# * various built-in commands including «command», «set», and «ulimit».
+#
+# Important for patching:
+#
+# (2) This script targets any POSIX shell, so it avoids extensions provided
+# by Bash, Ksh, etc; in particular arrays are avoided.
+#
+# The "traditional" practice of packing multiple parameters into a
+# space-separated string is a well documented source of bugs and security
+# problems, so this is (mostly) avoided, by progressively accumulating
+# options in "$@", and eventually passing that to Java.
+#
+# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+# see the in-line comments for details.
+#
+# There are tweaks for specific operating systems such as AIX, CygWin,
+# Darwin, MinGW, and NonStop.
+#
+# (3) This script is generated from the Groovy template
+# https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+# within the Gradle project.
+#
+# You can find Gradle at https://github.com/gradle/gradle/.
