About

Twitter (X) 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

This app posts to X directly from a workflow — plain text, or a tweet with an image or GIF attached — deletes a tweet, and reads back a specific one by id. Search reaches tweets from the last seven days, and a user can be looked up by username or read by their own recent tweet history.

Liking and retweeting are both supported and resolve to the authenticated user’s own account automatically, matching how X’s API itself scopes those actions. Authentication runs through OAuth with PKCE, X’s only supported flow for acting as a user, with a refresh token requested up front so a connection doesn’t need reauthorizing every two hours.

Good for posting scheduled or triggered content, monitoring recent mentions or a search term, and pulling a user’s tweet history into another system. Since 2026, most X API usage bills per request rather than through a flat free tier, worth knowing before wiring this into anything high-volume.

Build with Twitter (X)

Three routes to the same 8 actions. The Workflow tab is generated from Twitter (X)'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 Tweet

tweet-create

Post a tweet, optionally with one image/GIF attached, a reply, or a quote tweet.

Delete Tweet

tweet-delete

Delete a tweet owned by the authenticated user.

Get Tweet

tweet-get

Look up a single tweet by ID.

Like Tweet

tweet-like

Like a tweet as the authenticated user.

Retweet

tweet-retweet

Retweet a tweet as the authenticated user.

Search Recent Tweets

tweet-search-recent

Search tweets from the last 7 days matching a query.

Get User by Username

user-get-by-username

Look up a user by their @handle.

Get User's Tweets

user-get-tweets

List a user's recent tweets.

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 Twitter (X)'s real ids.

+3 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 Twitter (X), 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 Twitter (X). 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: "tweet-create",
  payload: {
    // text: "<value>",
    // media: "<value>",
    // mediaMimeType: "<value>",
    // mediaCategory: "<value>",
    // replyToTweetId: "<value>",
    // quoteTweetId: "<value>",
  },
});

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

Give an AI agent Twitter (X) — without giving it Twitter (X)'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.twitter#tweet-get",
    "input": {
      "tweetId": "<tweetId>"
    }
  }
}

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 Twitter (X) 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

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

Request MCP access

Health checks

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

service

X platform status

No machine-readable status feed is documented for the X Developer Platform (developer.x.com/status is a human-readable dashboard only), so this app declares the absence rather than guessing at an undocumented endpoint.

quota

Rate-limit headroom (users.read bucket)

Reads x-rate-limit-* off GET /2/users/me. Reports only that endpoint's 15-minute window — X exposes no aggregate quota endpoint, and this does not reflect the pay-per-use dollar-credit balance (see README).
