About

Gotify ships in the w6w first-party pack. It declares 12 actions, 2 health checks, and the host runs its code in a sandbox that never sees the credential.

Overview

Gotify (https://gotify.net) is a small self-hosted server for sending and receiving push notifications — the kind a script, cron job or monitoring stack fires off (‘backup finished’, ‘disk 90% full’) without needing a phone number, an email relay or a SaaS account. This app puts that server behind a workflow: send a message, list and prune the messages already sent, and manage the two kinds of access token Gotify hands out — application tokens for the things that send, and client tokens for the things (and people) that read and manage.

Because Gotify is software you run yourself, there is no fixed hostname or shared vendor account: the connection asks for the server’s own URL alongside a client token, and every action reaches wherever that server actually lives.

Deliberately out of scope: deleting an application or a client. Gotify gates both behind a freshly-elevated client session (a WebAuthn re-authentication ceremony, 403 session not elevated otherwise) that a stored API credential has no way to perform — see the README for the full explanation. Also out of scope: application images, plugins, the WebSocket message stream, OIDC/local login, and user administration — each is its own surface, and none is the daily loop of sending and triaging notifications.

Build with Gotify

Three routes to the same 12 actions. The Workflow tab is generated from Gotify's own manifest and carries its real ids, so it is copy-pasteable; the Code and CLI examples are the same call for any action on any app, so every app-specific value in them is a blank you fill in.

Create application

application-create

Create an application (a message sender) and mint its token.

List applications

application-list

List the applications (message senders) on this account.

Update application

application-update

Rename an application or change its default priority.

Create client

client-create

Register a new client and mint its token.

List clients

client-list

List the clients (receivers/managers) registered on this account.

Update client

client-update

Rename a client, or change its inactivity expiry.

Delete a message

message-delete

Permanently delete one message by id.

Delete all messages

message-delete-all

Permanently delete every message, or every message for one application.

List messages

message-list

List messages, optionally scoped to one application.

Send message

message-send

Push a notification through Gotify.

Get current user

user-get

The account the connection's client token belongs to.

Get version

version-get

The Gotify server version, commit and build date for this connection.

A workflow step names the app and the action, and the editor fills in the connection when you pick one. This is the Step shape from the workflow spec, carrying Gotify's real ids.

{
  "manifestVersion": "2",
  "name": "gotify-example",
  "steps": [
    {
      "id": "application-create",
      "uses": {
        "app": "io.w6w.gotify",
        "action": "application-create",
        "connection": "conn_YOUR_CONNECTION_ID"
      },
      "with": {
        "name": "<name>"
      }
    }
  ]
}

+7 more actions available

Every app-specific value here is a blank you have to fill in. An app action is reached through the connection that authenticates it, so the address is a connection id, not the app id — and connections belong to your account, so a public page cannot know yours. Create one for Gotify, then fill in the three blanks: conn_YOUR_CONNECTION_ID, the action key, and the parameters that action declares. The call itself is real — the shape is transcribed from the studio's own snippet builder, which prints the same kind of blanks — but nothing in it is specific to Gotify. The Workflow tab is where this app's real ids are.

Install
npm install @w6w/sdk
yarn add @w6w/sdk
pnpm add @w6w/sdk
deno add npm:@w6w/sdk
Code
import { W6wClient, isActionRun } from "@w6w/sdk";

// Reads W6W_BASE_URL and W6W_TOKEN from the environment when omitted.
const client = new W6wClient();

const envelope = await client.run({
  urn: "conn_YOUR_CONNECTION_ID",
  action: "application-create",
  payload: {
    name: "<value>",
    // description: "<value>",
    // defaultPriority: "<value>",
  },
});

if (isActionRun(envelope)) console.log(envelope.value);
Install the CLI
npm install -g @w6w/cli
CLI
w6w run conn_YOUR_CONNECTION_ID --action application-create --payload '{"name":"<value>"}'

Give an AI agent Gotify — without giving it Gotify's credentials. One MCP endpoint exposes every app, function and workflow the caller is entitled to, as tools it can discover and run. Access is granted per team while we onboard.

One tool call
{
  "name": "w6w_invoke",
  "arguments": {
    "ref": "app:io.w6w.gotify#application-create",
    "input": {
      "name": "<name>"
    }
  }
}

Every tool names its target with a single ref. The app: form above doesn't name a connection at all — the host resolves which of the caller's Gotify connections to sign with, and refuses rather than guesses when the answer is ambiguous.

What the agent gets

Credentials it can't read

The token is attached host-side, at the moment of the call. It is never a tool argument, never in the model's context, and never in a transcript — so a prompt injection has nothing to exfiltrate.

A tool surface scoped to the caller

Tools are derived per end user from what that person has actually connected and is entitled to — not one shared bot identity carrying the union of everyone's access.

A durable workflow in one call

Multi-step work runs on the workflow engine and returns a run handle the agent can poll — retries, branching and state survive the conversation that started them.

Health-aware discovery

Gotify's declared health checks are on the surface too, so an agent can tell "the vendor is down" from "your credential expired" before it burns a retry on either.

The MCP surface is part of the hosted platform. Gotify itself is MIT, and the runtime that executes it is source-available (FSL).

Request MCP access

Health checks

Gotify declares its own checks, so its health is a property of the app rather than something the host guesses at.

dependency

Gotify instance healthy

This connection's own server, via its unauthenticated /health endpoint. Sends no credential — an expired token must not make the server look down.
