Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Signal MCP show my latest GitHub commits"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
The Model Context Protocol (MCP) server powers Signal’s live integrations. It connects the system to GitHub activity, Spotify listening history, and blog content, providing real-time data that makes the portfolio feel alive.
The MCP server is a lightweight Express service that:
Handles GitHub activity integration
Connects to Spotify for “Now Playing” and recent history
Converts blog RSS feeds into consumable JSON
Exposes MCP-compliant endpoints so the backend can call tools through OpenRouter
It doesn’t interact with models directly. Instead, it responds when the backend orchestrates a tool call, returning structured data that can be streamed back into the conversation.

The MCP server acts as Signal’s live data provider, bridging the system to external APIs.
Runtime: Node.js
Framework: Express
Protocol: Model Context Protocol (MCP) SDK
Integrations: GitHub REST API, Spotify Web API, Blog RSS feed
Dev tooling: ESLint, Prettier, Husky, and shared configs via dev-config
Signal’s services can be run locally, but setup involves multiple moving parts.
For now, the easiest way to explore Signal is the live demo.
Future work may include a simplified docker-compose flow for local development.
The MCP server reflects how I approach integration boundaries and system interoperability. By isolating third-party APIs behind a single protocol-compliant service, the architecture stays modular and secure. This design makes it easier for teams to extend or swap integrations without affecting the rest of the system. This is a principle I carry into larger engineering projects.
