What is the Sondehub MCP server?

Connect Sondehub to Claude, Cursor or any other MCP client and it stops being a tab you switch to. SDK to access SondeHub open data, and helpers for uploading telemetry. The sondehub mcp server is what makes that connection.

What the server does

This repository contains: * A uploader class for submitting high-altitude balloon telemetry data to SondeHub-Amateur * A simple realtime streaming SDK for the sondehub.org V2 API (both radiosondes, and amateur balloons).

Installation

The server ships on PyPI as sondehub, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • Contacts — You can often find us in the #highaltitude IRC Channel on Libera Chat
  • Filtering — To specify a particular serial number, or multiple serial numbers to subscribe to, you can pass these in as a list in the sondes argument: python

Worth knowing first

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Where it fits

Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Sondehub's toolset — Contacts, Filtering — is a fair guide to whether it matches your workflow. It is maintained by Michaela; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
