How to Set Up and Use PeopleInSpace

The PeopleInSpace MCP server is a Kotlin Multiplatform project that exposes a live feed of people currently in space as an MCP tool, allowing AI assistants like Claude to answer real-time questions about astronauts aboard the ISS and other spacecraft. Built with the Kotlin MCP SDK and sharing code with SwiftUI, Jetpack Compose, and web clients in the same repository, it demonstrates how KMP libraries (Ktor, SQLDelight, Koin) can be reused across an MCP server and other platform clients. Developers exploring Kotlin MCP server development or KMP architecture will find it a practical reference implementation.

Prerequisites

  • Java 17 or later (JDK required to build and run the Kotlin server)
  • Gradle (the project includes a Gradle wrapper, no separate install needed)
  • Claude Desktop or another MCP-compatible client
  • Git to clone the PeopleInSpace repository
1

Clone the PeopleInSpace repository

Clone the full monorepo which contains the mcp-server module alongside other platform clients.

git clone https://github.com/joreilly/PeopleInSpace.git
cd PeopleInSpace
2

Build the MCP server fat JAR

Run the shadowJar Gradle task inside the mcp-server module to produce a self-contained executable JAR that bundles all dependencies.

./gradlew :mcp-server:shadowJar
3

Locate the built JAR

After the build completes, the JAR is placed in the mcp-server build output directory. Note the full path — you will need it in the next step.

ls mcp-server/build/libs/serverAll.jar
4

Configure Claude Desktop

Open Claude Desktop settings, select Developer Settings, then Edit Config. Add the MCP server entry pointing to the JAR you just built.

5

Restart Claude Desktop and verify

Restart Claude Desktop so it picks up the new configuration. The PeopleInSpace MCP server will be launched automatically. Ask Claude how many people are in space to verify the tool is working.

PeopleInSpace Examples

Client configuration

Add this entry to your Claude Desktop claude_desktop_config.json. Update the path to match the actual absolute path to serverAll.jar on your machine.

{
  "mcpServers": {
    "kotlin-peopleinspace": {
      "command": "java",
      "args": [
        "-jar",
        "/absolute/path/to/PeopleInSpace/mcp-server/build/libs/serverAll.jar",
        "--stdio"
      ]
    }
  }
}

Prompts to try

Once connected, ask Claude questions about the people currently in space.

- "How many people are currently in space?"
- "Who is aboard the ISS right now?"
- "List all people in space and their nationalities"
- "Which spacecraft are currently crewed?"

Troubleshooting PeopleInSpace

shadowJar task not found or build fails

Ensure you are running the task on the correct subproject: ./gradlew :mcp-server:shadowJar. If Gradle complains about Java version, verify JAVA_HOME points to JDK 17+ with java -version.

Claude Desktop shows the server as disconnected

Verify the JAR path in your config is absolute (not relative). Test manually: java -jar /path/to/serverAll.jar --stdio — if no error appears the server started correctly.

Data is stale or API calls fail

The server fetches live data from the Open Notify API. Ensure the machine running the server has outbound internet access. Firewall or VPN rules blocking https://corquaid.github.io/international-space-station-APIs/ will cause failures.
