# Connect LFG Alarm to n8n AI agents · https://lfg.gm/agents/n8n · Updated 2026-10-19 To connect LFG Alarm to n8n, make a personal key in LFG Alarm under Settings > Connected AI apps, then add an **MCP Client Tool** to an AI Agent node with the address https://mcp.lfg.gm, the HTTP Streamable transport and Bearer Auth set to your key. The agent in your workflow can then set alarms that ring on your phone. For a workflow that should simply ring you when something happens, there is an even shorter way: an HTTP Request node that calls an anything alarm's private link. LFG Alarm is a social alarm clock for iPhone and Android: alarms for times and moments, shared by link so every phone that joined rings together. ## Before you start - **Get the LFG Alarm app on your phone** from Google Play or the App Store, and sign in. n8n makes or triggers the alarms; the app is what rings them. - **n8n with the MCP Client Tool node** (it ships with n8n, cloud or self-hosted, and works with the AI Agent node). - **A personal key** for the agent route, since an n8n workflow cannot do a sign-in. Make one below. A key acts as you. Any workflow that holds it sets alarms on your phone, so keep it in an n8n credential, not pasted into a node, and keep it out of workflows that strangers can trigger, such as a public chat or form. There is no LFG Alarm node for n8n yet; this page uses n8n's own nodes. ## Make a key 1. In LFG Alarm, open **Settings** > **Connected AI apps**, on [lfg.gm](https://lfg.gm) or in the app. 2. Tap **Make a key**, name it after the workflow (for example "n8n"), and tap **Make the key**. 3. The key is shown once, with **Copy** and **Done**. Copy it, then tap **Done**. Keys start with `lfg_pat_`, work only at the LFG Alarm MCP server, and allow 60 calls a minute and, each day, up to 50 new alarms, 50 comments and 20 uploads. A key has the same plan limits as signing in. ## Ring your phone from a workflow The shortest path, and no key at all: when a workflow decides something needs a human, it rings an anything alarm. 1. In LFG Alarm, make an **Anything** alarm and copy its private link. 2. In n8n, add an **HTTP Request** node where the workflow should ring you. **Method:** `POST`. **URL:** the alarm's link. 3. Run the workflow. Your phone rings, and so do the friends you shared the alarm with. Good fits: an order over a set amount, a form from a VIP client, a failed backup, a price your own workflow computes. See [How to make any app, script or feed ring your phone](https://lfg.gm/webhook-alarm). ## Let an n8n agent set alarms 1. Add an **AI Agent** node with a chat model. 2. Under the agent's **Tool**, add **MCP Client Tool**. 3. **Endpoint:** `https://mcp.lfg.gm`. **Server Transport:** **HTTP Streamable** (not the deprecated SSE). 4. **Authentication:** **Bearer Auth**, and create a credential with your `lfg_pat_` key. (Header Auth also works: name `Authorization`, value `Bearer lfg_pat_...`.) 5. **Tools to Include:** **Selected** is the safe choice for an automation. Pick what the workflow needs, for example `set_time_alarm` and `list_my_alarms`, and leave out `delete_alarm`. 6. In the agent's system message, say when to use it: "When a task needs a person to act at a set time, set an LFG Alarm and report the time it rings." ## Try it Once the MCP Client Tool is attached, send the agent: **Try this.** Paste it into ChatGPT, Claude, Grok or another AI agent that has the LFG Alarm connector (https://mcp.lfg.gm), not into the LFG Alarm app. The person needs the LFG Alarm app on their phone. > Use LFG Alarm to set a one-off time alarm for 7:30 tomorrow morning called "Review the weekly report". Then tell me the date and time it will ring. Why it works: A one-off time alarm and a confirmation, which proves the credential, transport and tool are wired up. More ideas: a schedule trigger that asks the agent each Sunday to set the week's early alarms from a calendar, or a workflow that reads an event email and sets an event alarm from its Luma or Partiful link. Through a key, LFG Alarm can set time, price, post, event, wallet, trader and anything alarms, pick a sound or a look from the library, and add your friends or a whole group once you confirm. See [Using LFG Alarm from your AI agent](https://lfg.gm/wiki/ai-agents). ## If it does not work - **The tool list is empty or the node errors on connect.** Check the transport is **HTTP Streamable** and the endpoint is `https://mcp.lfg.gm` exactly. - **401 Unauthorized.** The credential must send `Bearer ` and the key. Make a new key if this one was removed. - **Adding friends stalls.** LFG Alarm lists who it would add and waits for a yes. A workflow with nobody to answer should set private alarms, or name only people already confirmed. ## Questions ### Is there an LFG Alarm node for n8n? Not yet. Until there is, the HTTP Request node rings an anything alarm, and the MCP Client Tool lets an agent set alarms. ### Do I need a key to ring my phone from n8n? No. An anything alarm's private link needs no key: anything that POSTs to it rings the alarm. Keep the link private; it is the alarm's own password, and you can replace it from the alarm's page. A run inside the alarm's quiet time (1 minute to 1 hour, set when you made it) answers 429 and does not ring again. ### Can several people use one workflow? Every alarm set through one key lands on the key owner's account. For a team, each person makes their own key, or the workflow rings a shared friends alarm that everyone joined. ## Learn more - [How to make any app, script or feed ring your phone](https://lfg.gm/webhook-alarm) - [Using LFG Alarm from your AI agent](https://lfg.gm/wiki/ai-agents) - [Connect LFG Alarm to another AI app](https://lfg.gm/agents) ## Sources and further reading - [n8n docs: MCP Client Tool node](https://docs.n8n.io/integrations/builtin/cluster-nodes/sub-nodes/n8n-nodes-langchain.toolmcp/) - [n8n docs: HTTP Request node](https://docs.n8n.io/integrations/builtin/core-nodes/n8n-nodes-base.httprequest/) LFG Alarm is not affiliated with n8n. ## Keep exploring - [Connect LFG Alarm to your AI app](https://lfg.gm/agents.md): The LFG Alarm MCP server: set alarms from ChatGPT, Claude, Grok, Gemini, OpenClaw and more, and they ring on your phone. - [Connect LFG Alarm to ChatGPT](https://lfg.gm/agents/chatgpt.md): Add LFG Alarm to ChatGPT with the address mcp.lfg.gm, sign in once, and ask ChatGPT to set alarms that ring on your phone. - [Connect LFG Alarm to Claude](https://lfg.gm/agents/claude.md): Add LFG Alarm to Claude as a custom connector, sign in once, and ask Claude to set alarms that ring on your phone.
