Most developer tooling work still happens through a UI a human drives. Cumulocity MCP server moves it into the conversation instead. A Python-based server that provides Cumulocity IoT platform functionality through the MCP (Model Control Protocol) interface. This server enables seamless interaction with Cumulocity's device management, measurements, and alarm systems.
mcp-server-c8y on PyPI is all you need. Most clients run it directly, so configuration is a few lines and a restart.
The server publishes 5 tools. What each one is for:
your-tenant-id — Your Cumulocity tenant IDyour-username — Your Cumulocity usernameyour-password — Your Cumulocity passwordMeasurements — The Measurements tool exposed by this serverAlarms — The Alarms tool exposed by this serverConfiguration is passed through the environment: C8Y_BASEURL, C8Y_TENANT, C8Y_USER, C8Y_PASSWORD, YOUR_BASE64_AUTH_TOKEN. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
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. Cumulocity's toolset — your-tenant-id, your-username, your-password and 2 more — is a fair guide to whether it matches your workflow. It is maintained by Cumulocity-IoT; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
