Submit and read posts and comments, vote, search, and look up identity on Reddit.
About
Reddit ships in the w6w first-party pack. It declares 8 actions, 2 health checks, and the host runs its code in a sandbox that never sees the credential.

Overview
Reddit submits and reads posts and comments, votes, searches, and reads back the connected account’s own identity against Reddit’s OAuth-authenticated API. Posts and comments can be submitted and listed by subreddit or sort order, a specific post fetched directly by its id, and search run either sitewide or scoped to one subreddit.
Authentication uses Reddit’s standard OAuth2 flow with the minimal set of scopes each action actually needs, requesting a permanent grant so a refresh token comes back rather than requiring the user to reconnect once the initial token expires. Reddit’s own quirks are handled directly rather than left for a workflow to discover: write endpoints are form-encoded rather than JSON, and a validation failure can arrive as an HTTP 200 with the real error nested inside the body, so both are normalized into an ordinary rejected call.
Comment threads are read one level deep — top-level comments only, without walking nested replies — and moderation, editing, deleting, saving and subreddit management are left out entirely, since none of those were part of this app’s requested action set.
Build with Reddit
Three routes to the same 8 actions. The Workflow tab is generated from Reddit'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.
List Subreddit Posts
post-list List posts from a subreddit, sorted by hot, new, rising, top, or controversial.
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 Reddit's real ids.

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 Reddit, 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 Reddit. The Workflow tab is where this app's
real ids are.

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.reddit#comment-list",
"input": {
"subreddit": "<subreddit>",
"postId": "<postId>"
}
}
}
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 Reddit 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
Reddit'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. Reddit itself is MIT, and the runtime that executes it is source-available (FSL).
Health checks
Reddit declares its own checks, so its health is a property of the app rather than something the host guesses at.

GET https://www.redditstatus.com/api/v2/summary.json (Statuspage.io feed).
Rate-limit headroom
Reads X-Ratelimit-* off GET /api/v1/me. Reddit shares one bucket across all endpoints for a given OAuth client, so this is a whole-app reading.
