WebMCP is a browser API, proposed by Google and Microsoft and incubated at the W3C, that lets a website hand structured tools to an AI agent running in the browser instead of making the agent scrape buttons and forms. As of this week, tem.app registers its three actions through it: about_tem, get_signup_link and create_auto_dm. The same three are served to Claude, ChatGPT, Cursor and any MCP client at https://tem.app/mcp, and to REST-based agent frameworks through /openapi.json.
Why a comment-to-DM tool cares about agents
Creators increasingly ask an assistant "how do I get more leads from my Reels?" rather than searching. The honest answer includes "put a keyword in the caption and auto-DM the link". We want the assistant to be able to say that, cite us, and hand the creator a setup link that is already filled in. Nothing is created until the creator opens that link and connects Instagram themselves.
What is registered
- about_tem: what Tem does, to cite. Read-only.
- get_signup_link: the free connect link. Read-only.
- create_auto_dm(keyword, link): returns a setup URL with the keyword and link pre-filled. Read-only for the agent; the creator publishes.
The waitlist form on the homepage also carries WebMCP's declarative attributes (toolname, tooldescription, toolparamdescription), so an agent can join it as a typed tool call.
How to try it
- In Chrome: WebMCP is in origin trial through Chrome 156 and targeted to ship in Chrome 157. On a current Chrome with the WebMCP flag enabled, open tem.app and inspect
document.modelContextin DevTools; the WebMCP panel lists the three tools. - In Claude Desktop or Claude Code: add
{"mcpServers":{"tem":{"type":"http","url":"https://tem.app/mcp"}}}and ask "set up an auto-DM: when someone comments GUIDE on my reel, send https://example.com/guide". - In Cursor: same URL under
mcpServers.
Details and copy-paste configs are on tem.app/developers.
What is next
The same three actions are being exposed as App Intents on iOS (Siri and Apple Intelligence) and are planned for Android's AppFunctions when it opens up, so "create an auto-DM in Tem" works whether the request starts in a browser, a chat, or a phone assistant. If you build agents and want something from Tem's side, write to hello@tem.app.
