thingctx

thingctx is a Python library that turns a W3C Web of Things Thing Description into tools an AI agent can call. The description is a JSON document naming a system's actions and a transport for each; thingctx runs every call over that transport. No server per integration.

You can add a policy gate that decides each call before any transport runs: allow reads, deny writes, or ask a human first. The binding holds the credential; the model never sees it.

First run

pip install thingctx

The base install pulls no dependencies. This runs with no keys and no network:

import asyncio

import thingctx
from thingctx.contrib.time import make_time_handler

td = {
    "@context": "https://www.w3.org/2022/wot/td/v1.1",
    "id": "urn:demo:clock",
    "title": "Clock",
    "securityDefinitions": {"nosec_sc": {"scheme": "nosec"}},
    "security": ["nosec_sc"],
    "actions": {
        "getCurrentTime": {
            "input": {
                "type": "object",
                "properties": {"timezone": {"type": "string"}},
            },
            "forms": [{"href": "local://getCurrentTime"}],
        }
    },
}


async def main():
    client = thingctx.ThingClient(
        tds=[td], bindings=[thingctx.LocalBinding(make_time_handler())]
    )
    tools, invoke = client.as_tools()
    print("tools:", [t["function"]["name"] for t in tools])
    print(await invoke("clock__getCurrentTime", {"timezone": "UTC"}))


asyncio.run(main())

Agent loop

Install 'thingctx[llm,http]', set your provider key, import thingctx, and inside an async function:

host = await thingctx.from_url("https://example.com/device.td.json")
print(await host.chat("summarize the device's status"))

from_url accepts any URL that serves a Thing Description.

Closed agent (Claude Desktop, VS Code)? Install 'thingctx[mcp]' and bridge a folder of descriptions:

thingctx-mcp ./registry/
