How to Post to X (Twitter) and LinkedIn Directly from Claude Code, Cursor & Grok Bot via MCP

QUICKSTART CODE / MCP CONFIGURATION

// ~/.cursor/mcp.json or .mcp.json
{
  "mcpServers": {
    "nuntior": {
      "url": "https://mcp.nuntior.com/mcp"
    }
  }
}

// Prompt inside Cursor / Claude Code / Grok Bot:
// "Register a Nuntior workspace for dev@company.com, connect my X and LinkedIn accounts,
//  and publish our v2.4 changelog with the link placed in the first X reply."

1. Zero-Browser Onboarding with account_register

Unlike traditional social APIs that force you to sign up in a browser first, Nuntior exposes the account_register MCP tool. Your agent calls account_register with your email and workspace name, immediately receiving a live nnt_live_... API key and default profileId.

2. Stage-Then-Auth OAuth Flow ("Return to your Agent")

When you ask your agent to publish to X or LinkedIn before connecting an account, Nuntior stages the post and returns a 1-Click OAuth link (https://nuntior.com/v1/oauth/x/start?...). As soon as you click Authorize, Nuntior automatically publishes the staged post and closes the browser tab so you never leave your agent conversation.

3. Cross-Posting to LinkedIn Personal & Organization Pages

Nuntior supports both LinkedIn Personal profiles and LinkedIn Organization Pages (Community Management API) out of the box, converting Markdown formatting and attaching canonical OpenGraph previews automatically.
