OpenAI Codex is OpenAI’s CLI agent for software development. You can connect it to TryPost’s MCP server to manage your social media scheduling with natural language.

​
Prerequisites

  • Codex CLI installed (npm install -g @openai/codex)
  • A TryPost Cloud account with an active subscription (plans and billing)

​
Setup

1

Open the configuration file

Edit ~/.codex/config.toml and add the TryPost server:
No Authorization header — Codex discovers OAuth from the URL.
2

Sign in via codex mcp login

Run the OAuth flow so Codex caches the token:
Codex opens your browser to TryPost; approve the request and return to the terminal.
3

Verify the connection

Start Codex and ask:
Codex uses TOML for configuration (not JSON). For sandboxed environments where the default callback port isn’t reachable, set mcp_oauth_callback_port or mcp_oauth_callback_url in config.toml.
