Your AI assistant, now publishes.

Hand your CrossPoster workspace to Claude Desktop, Cursor, or ChatGPT. They get a toolbelt — drafts, publishing, audits, personas, autonomous scheduling. You get one OAuth consent screen and zero copy-paste between tabs.

CrossPoster speaks Model Context Protocol (MCP) — the open standard every modern AI assistant supports.

Add CrossPoster to your assistant

One click for Cursor, or paste the server URL into any client's connector settings. OAuth runs the first time you connect — no keys.

CursorAdd to CursorDeep-link install — Cursor opens and adds CrossPoster as an MCP server.

Claude & ChatGPTAdd via ConnectorsSettings → Connectors → Add custom connector → paste the URL.

What you can do

Three concrete examples. Same OAuth-scoped access for all three.

Schedule a LinkedIn post for tomorrow morning

Draft a LinkedIn post about our Q3 launch — focus on the new agent features — and schedule it for tomorrow at 9am London time.

Creates a draft, generates a caption tuned for LinkedIn voice, suggests publish time, schedules. Tools: create_draft → generate_caption → suggest_publish_time → schedule_post.

Generate a week of Instagram content from a single brief

Plan 5 Instagram posts for next week. Theme is 'behind the scenes at a startup'. Generate the images too. I'll review before anything ships.

Creates a calendar, generates captions + images per day, presents each draft for review. Nothing publishes until you explicitly approve. Tools: create_content_calendar → generate_image (×5).

Switch personas mid-conversation

Switch to my 'Founder thought leadership' persona, then audit my latest LinkedIn draft and tell me if it actually sounds like a founder, not like a marketer.

Switches active persona for the session, then runs a content audit scoring the draft across 7 dimensions. Tools: switch_persona → run_content_audit.

Claude Desktop, Claude.ai & ChatGPT

These connect through the app's own UI — no config file. Open Settings → Connectors → Add custom connector, and paste the server URL:

https://mcp.crossposter.tech/mcp

OAuth runs on first connect — sign in and approve the scopes. ChatGPT connectors need a paid plan (Plus, Pro, Business, or Enterprise).

Cursor

Use the Add to Cursor button above, or add this to ~/.cursor/mcp.json. Cursor discovers OAuth from the URL — no client ID or keys to paste.

  "mcpServers": {
    "crossposter": {
      "url": "https://mcp.crossposter.tech/mcp"
    }
  }
}

Available scopes

Each scope grants a fixed capability cluster. You approve them on the consent screen when you connect; revoke individual tokens anytime in Integrations.

Scope	What it grants
tools.read	Read drafts, posts, platforms; recall memory.
tools.drafts.write	Create, edit, transform drafts.
tools.content.generate	Generate new content, improve captions.
tools.media.generate	Generate AI images, videos, edits.
tools.publish	Publish or schedule posts.
tools.audit	Score content; run compliance checks.
tools.memory.write	Save / delete / clear memories.
tools.workflows	Create calendars, request team approval.
tools.persona	Switch + configure personas.
tools.autonomous	Configure autonomous publishing thresholds.

How OAuth works

You add CrossPoster to your AI client (the buttons above, or paste the URL into its connector settings).
On first connect, the client opens a browser tab to app.crossposter.tech.
You sign in (if you weren't already) and approve the scopes the client requested.
The client receives an access token via PKCE + RFC 7591 dynamic registration. No keys to manage.
You revoke or rotate any time at /settings/integrations.

Already using an API key?

Legacy cp_live_* keys keep working — no breaking changes. Add them to your MCP client as x-api-key headers. OAuth is the recommended new path; API keys remain available.
