simple-vertx

This MCP server is a simple Model Context Protocol server implemented in Vert.x. It exposes MCP endpoints that clients can interact with using standard MCP tooling and example integrations such as Claude Desktop, n8n, and Postman to verify behavior. The server is designed to respond to MCP context requests, publish context changes, and support typical MCP workflows used for testing and demonstration. To begin, ensure the server jar is built and running, then connect your MCP clients to the server’s listening port to exchange context data and validate the protocol exchanges.

Prerequisites:

• Java JDK 11 or newer
• Maven or Gradle (depending on the project build setup)
• Git

Installation steps:

1. Clone the repository:

git clone <repository-url>
cd <repository-directory>

2. Build the MCP server jar (adjust command to your build tool if needed):

./mvnw clean package

or

./gradlew clean build

3. Run the MCP server:

java -jar build/libs/simple-vertx-mcp-server.jar

4. Verify the server is listening on the configured port (default 8080):

curl http://localhost:8080/health

5. If you use a Docker-based approach, you could containerize and run it as:

# Dockerfile example would package the jar; run container:
docker run -p 8080:8080 simple-vertx-mcp-server:latest

Tips:

• Ensure Java is installed and JAVA_HOME is set if the server relies on it.
• Use the health endpoint (if provided by the server) to verify runtime readiness.
• When integrating with Claude Desktop, n8n, or Postman, configure MCP request payloads to match the MCP protocol version your server implements.
• If you encounter port conflicts, adjust the server's port configuration in the app properties or command-line options as supported by the build.
• Enable verbose logging (MCP_LOG_LEVEL=DEBUG) temporarily to diagnose protocol exchanges.
