Thingctx MCP Server

thingctx turns a description of any API, device, or local process into tools an AI agent can call: authorized per operation, over the system's own transport, and the agent never holds your keys. The description is a W3C Web of Things Thing Description (a TD), a plain JSON file naming what the system can do. Write one, or compile it from an OpenAPI spec. The described system is the server, so you run no server per…

Claude Code

claude mcp add thingctx-thingctx -- uvx thingctx

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "thingctx-thingctx": {
      "command": "uvx",
      "args": [
        "thingctx"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

What is Thingctx?

Is Thingctx still maintained?

Yes - as of 2026-08-25, its last commit was 2026-08-24 and it shipped 4 releases in the last 90 days. We re-verify nightly.

How do I install Thingctx?

Does Thingctx run locally?

Yes - it's a stdio server: it runs on your machine (via uvx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
