Hello World Example ​

This is a minimal example demonstrating the basic functionality of the Camel Integration Capability.

What It Does ​

The example exposes a single route that:

  1. Accepts a greeting message as input
  2. Logs it to the console
  3. Returns a formatted greeting response

Files ​

  • hello-quote.camel.yaml: A simple Camel route that processes greeting messages
  • hello-quote-rules.yaml: MCP tool configuration exposing the route to AI agents

Running the Example ​

Prerequisites ​

  • Java 21 or higher
  • The Camel Integration Capability JAR built or downloaded
  • A running Wanaku MCP Router instance
  • OAuth2/OIDC credentials (or authentication disabled in Wanaku)

Start the Service ​

bash
java -jar ../../camel-integration-capability-runtimes/camel-integration-capability-main/target/camel-integration-capability-main-*-jar-with-dependencies.jar \
  --registration-url http://localhost:8080 \
  --registration-announce-address localhost \
  --name hello-world \
  --routes-ref file://$(pwd)/hello-quote.camel.yaml \
  --rules-ref file://$(pwd)/hello-quote-rules.yaml \
  --client-id wanaku-service \
  --client-secret your-secret

Test via AI Agent ​

Once registered with Wanaku, AI agents can invoke the sends-greeting tool:

text
AI: Send a greeting with message "World"

Expected response:

text
Hello World from route-3104

Key Concepts ​

Automatic Parameter Mapping ​

This example uses automatic parameter mapping. The MCP parameter wanaku_body is automatically mapped to the Camel message body because it follows the naming convention wanaku_body.

The Camel route accesses it via ${body}:

yaml
- log:
    message: Hello ${body}

Route Exposure ​

The rules file defines which routes are exposed as MCP tools:

yaml
tools:
  - sends-greeting:
      route:
        id: "route-3104"

This makes the route available to AI agents via the Wanaku MCP Router.
