The Muse directory application is submitted, with requirements still outstanding. Our client setup guides explain the custom connections available today. API and MCP access needs a posterly plan with API access. New accounts can start with a 7-day free trial: a card is required, you are charged on day 8 unless you start the paid plan sooner, and API and MCP use is limited during the trial.

67 MCP tools covering 103 actions
The local stdio package exposes 67 tools covering 103 actions, including public setup and signup tools. The hosted HTTP endpoint at /api/mcp exposes the same authenticated catalog: 64 tools covering 100 actions. Each tool lists its views or actions underneath. Hosted HTTP tool calls are JSON-only, so direct media uploads there are limited to small base64 files.

No posterly account yet?
An AI agent can install the MCP server without an API key, call start_signup, and poll get_signup_session while you pay and set a password in the browser.
{
"mcpServers": {
"posterly": {
"command": "npx",
"args": ["-y", "posterly-mcp-server@latest"]

}After posterly shows the API key, add POSTERLY_API_KEY to unlock scheduling and social account connection tools.
Enable API access in posterly
Buy plan + API in one checkout from this page (or go to Dashboard → API & MCP if you already paid). Hosted connectors use posterly sign-in. Create an API key only for a local or Bearer-token connection.
Add posterly to your AI client
Choose your client below. Hosted connectors use the server URL and posterly sign-in. Local clients use an API key:
Claude → Settings → Connectors → Add custom connector. Paste the hosted URL, then connect and sign in to posterly. Leave the advanced OAuth fields empty.
Hosted MCP, no npm install requiredServer URL: https://www.poster.ly/api/mcp
Authentication: OAuth (sign in to posterly and press Allow)Not sure how? Copy and paste into your AI assistant. It'll handle the rest.
Check the connection and start posting
After connecting, start a new chat if needed. Restart only if you changed a local config file. You should see "posterly" in the tools list. Try saying: "Check the posterly MCP status, then list my posterly accounts".
Using a browser-based agent? Skip the install.
Claude in Chrome, ChatGPT (developer mode apps), Cursor in browser, Grok Bot (xAI's cloud agent), and any other remote MCP client can talk to posterly directly over HTTP. No local subprocess needed; it is the same key, same paywall, and same 64 hosted HTTP MCP tools covering 100 actions. Because this transport is JSON-only, use local stdio MCP, public media URLs, or signed-upload capable clients for larger file uploads. Dedicated connect pages: Claude, ChatGPT, Gemini, Cursor, Grok Bot, Poke, Hermes, OpenClaw, and Muse, Manus, and Cue. Gemini Spark uses the same URL. OAuth sign-in from gemini.google.com is still being validated. Manus and Cue are Custom MCP by URL (www required). A verified live connect for those clients is still being validated. First-schedule walkthroughs: ChatGPT, Claude, Cursor, Grok Bot, Poke, Hermes, OpenClaw. Media bodies: Solving the 4MB MCP limit.
