About

Discourse ships in the w6w first-party pack. It declares 26 actions, 3 health checks, and the host runs its code in a sandbox that never sees the credential.

Overview

Discourse is community forum software, and this app reads and writes topics, posts, categories, users and groups on any Discourse forum — self-hosted or Discourse-hosted — over its REST API.

It covers the full posting lifecycle: creating topics, replies and private messages, liking and deleting posts, and updating a topic’s status. On the community side, it manages categories, lists and manages group membership, and looks up or suspends users. A dedicated search action exposes Discourse’s own filter syntax — by user, category, tag, date range and more — as a single query string, rather than reassembling it from a dozen separate parameters.

Because a Discourse forum lives at whatever domain its community chose rather than a fixed vendor host, this app connects to the specific forum a workflow is pointed at. Health checks reflect that: alongside Discourse’s own hosting-status page, each connection gets its own reachability check against its actual forum, so a self-hosted install is judged on its own uptime rather than on Discourse’s hosted service.

Build with Discourse

Three routes to the same 26 actions. The Workflow tab is generated from Discourse'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 Category

category-create

Add a category to the forum.

List Categories

category-list

Every category visible to the connection, with their numeric ids.

List Category Topics

category-topic-list

Topics inside one category.

Add Group Members

group-add-members

Add one or more users to a group. Existing members are left alone.

Get Group

group-get

Fetch a group by name — including the numeric id the membership actions need.

List Groups

group-list

Every group visible to the connection.

Remove Group Members

group-remove-members

Remove one or more users from a group.

Send Private Message

message-create

Open a private message thread with one or more users or groups.

Create Post

post-create

Reply to an existing topic.

Delete Post

post-delete

Remove a post. Soft by default; staff can restore it.

Get Post

post-get

Fetch a single post by id.

Like Post

post-like

Add a like to a post, as the connection's API user.

Update Post

post-update

Replace a post's Markdown body.

Search

search

Full-text search across topics, posts, users and categories.

Get Site Info

site-info-get

The forum's configuration payload — categories, groups, trust levels and the enum tables the rest of the API returns as bare integers.

Create Topic

topic-create

Start a new topic in a category.

Delete Topic

topic-delete

Remove a topic. Staff can still restore it unless the forum purges deletions.

Get Topic

topic-get

Fetch one topic with the first page of its posts.

List Latest Topics

topic-list-latest

The forum's latest topics, in the order the front page uses.

Set Topic Status

topic-set-status

Close, pin, archive or unlist a topic.

Update Topic

topic-update

Retitle a topic or move it to another category.

Create User

user-create

Register a new forum account.

Get User

user-get

Fetch a user's public profile by username.

List Users

user-list

Admin user directory, filtered by one of Discourse's six user flags.

Suspend User

user-suspend

Suspend an account until a given date, with a reason.

Update User

user-update

Change a user's display name or external identity mapping.

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 Discourse's real ids.

{
  "manifestVersion": "2",
  "name": "discourse-example",
  "steps": [
    {

+21 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 Discourse, 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 Discourse. 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: "topic-create",
  payload: {
    title: "<value>",
    raw: "<value>",
    // category: "<value>",
    // createdAt: "<value>",
    // embedUrl: "<value>",
    // externalId: "<value>",
    // autoTrack: "<value>",
  },
});

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

Give an AI agent Discourse — without giving it Discourse'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.discourse#category-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 Discourse 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

Discourse'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. Discourse itself is MIT, and the runtime that executes it is source-available (FSL).

Request MCP access

Health checks

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

service

Discourse hosting status

Component status from Status.io, the platform behind status.discourse.org. Covers Discourse's own hosting — a self-hosted forum is unaffected, which is why this check is informational and the per-connection `site` check carries the weight.

quota

API quota headroom

dependency

Forum reachable

Unauthenticated `GET /site/basic-info.json` against this connection's forum — the one Discourse endpoint exempt from the login gate, so it proves the host resolves AND that Discourse is serving JSON on it, even for a private forum.
