Haze.McpServer.Echo is a lightweight MCP (Model Context Protocol) server whose primary role is to participate in MCP-based workflows by handling context messages and providing a simple echo-style response for testing and debugging. The server is designed to be easy to deploy and integrate into a broader MCP ecosystem, acting as a minimal service that receives model contexts, possibly logs them, and returns an echoed or simplified acknowledgement to verify connectivity and basic message flow. Use this server to validate your MCP tooling or to serve as a deterministic endpoint in local development.

To interact with the server, start it with your chosen runtime (the project is configured to run as a Node.js project in this setup). Once running, you can point MCP clients at the host and port where the server is listening and send standard context messages. The server will process incoming MCP payloads and respond in a predictable manner, making it suitable for integration tests, smoke tests, and demonstrations of MCP tooling capabilities such as message construction, context binding, and round-trip verification.

Prerequisites:

• Node.js (LTS version recommended)
• Git

Install and run:

1. Clone the repository or download the release package git clone https://example.com/zaevi-haze.mcpserver.echo.git cd haze.mcpserver.echo

2. Install dependencies npm install

3. Start the server npm start

   or if a specific script is defined

   node path/to/server.js

4. Verify the server is running

   • Check the console for a listening/ready message
   • Send a test MCP payload to the configured endpoint and observe the echo response

Notes:

• Ensure any required environment variables are set prior to startup (see additional_notes for common options).
• If you are deploying in a container or cloud environment, ensure network security groups/firewall rules allow the MCP port.

Environment variables and configuration options:

• PORT: The port the MCP server will listen on (default if unspecified).
• MCP_HOST: Bind address for the server (e.g., 0.0.0.0 for accessibility).
• LOG_LEVEL: Adjust verbosity (e.g., debug, info, warn, error).

Common issues:

• If the server fails to start, verify Node.js is installed and dependencies are installed (npm install).
• If you see connection timeouts, confirm the host/port are reachable from the client and no firewall blocks the port.
• For debugging, enable verbose logging to capture incoming MCP messages and responses.

Configuration tips:

• Keep the echo behavior; it helps quickly validate basic MCP message flow without implementing full business logic.
• When integrating with other MCP tools, ensure message schemas match the expected MCP model context format and that IDs/messages are correctly constructed.
