Schedule posts from any AI agent
posterly works with ChatGPT, Claude, Hermes, Cursor, OpenClaw, and any tool that supports MCP or REST APIs. Tell your AI to post - posterly handles the rest across 11 platforms.
Always keep a human in the loop when using AI agents to post.
How it works
Three ways to connect your AI agent to posterly.
MCP Server
Run the posterly MCP server with npx or use the HTTP endpoint from Claude Desktop, Cursor, Windsurf, or Cline.
REST API
Use the posterly API with any agent that can make HTTP requests: ChatGPT, custom GPTs, or your own scripts.
OpenClaw Skill
Install the posterly skill for OpenClaw. Schedule posts from WhatsApp, Telegram, Slack, or Discord.
Built for agents that need to onboard a user
Agents can start paid signup, hand the user to checkout, then guide them through account authorization with live connection status.
POST /api/v1/signup
Paid API signup
Start a required-payment signup from the public API. Posterly returns checkout_redirect_url and poll_url so the chat can keep the user informed.
GET /api/v1/signup/sessions/{id}
Signup status polling
Report payment, password setup, and authorization progress while the user completes safe browser steps.
POST /api/v1/connect/{platform}/sessions
Browser OAuth handoff
Create a connection session for Instagram, Meta, YouTube, LinkedIn, X, Telegram, Bluesky, and the rest of the supported targets.
GET /api/v1/connect/sessions/{id}
Progress the agent can report
Poll the session while the user opens posterly, approves provider OAuth, enters credentials, or hits an error.
Works with your favourite AI tools
Any tool that supports MCP or HTTP requests can control posterly.
