Post to social media from Codex

Set it up

1. 1. Create an iHatePosting API key

   Sign in, open Settings → Developers and create a key. It starts with pk_live_ and is shown in full only once, so copy it before you leave the page.

2. 2. Add iHatePosting to Codex

   Add to the end of ~/.codex/config.toml. Your key does not go in this file.

   # ~/.codex/config.toml — add this at the end of the file.
   
   # Put the line IHATEPOSTING_API_KEY=pk_live_… in ~/.codex/.env, then restart Codex.
   # The CLI, the IDE extension and the ChatGPT desktop app read that file at startup.
   [mcp_servers.ihateposting]
   url = "https://ihateposting.com/mcp"
   bearer_token_env_var = "IHATEPOSTING_API_KEY"

3. 3. Ask it to post

   Tell Codex what you want to say and where. It saves a draft in iHatePosting unless you ask for the post to go out now or at a set time.

What is different about Codex

• bearer_token_env_var names the variable that holds your key; Codex reads it when it starts the server and sends it as a Bearer token. The simplest place for it is a line IHATEPOSTING_API_KEY=pk_live_… in ~/.codex/.env, which the CLI, the IDE extension and the ChatGPT desktop app load at startup; restart Codex after you change it. For the CLI you can instead export the variable in the shell you start Codex from, but a Codex background server that is already running keeps its old environment (codex app-server daemon restart reloads it). If the variable is missing or empty, Codex does not start this server and says so.
• There is no type setting in Codex's config — a url is what makes the entry a Streamable HTTP server.
• A project-level .codex/config.toml is read only in projects you have marked as trusted; the file in your home folder works everywhere.
• config.toml also holds your other Codex settings and MCP servers, so add this block at the end of the existing file rather than replacing it. Lines under a [section] header belong to that section, so pasting it at the top would swallow the settings below it. If you already have an [mcp_servers.ihateposting] block, replace that block instead of adding a second one.

OpenAI's own documentation: Codex MCP configuration

Nothing goes out unless you say so

Every post Codex writes is saved as a draft in iHatePosting unless you ask for it to be published now or at a set time. Publishing, rescheduling, retrying and deleting are marked as actions that change things, so clients that honour those markings ask you before they run them. Deleting a post in iHatePosting never removes one that is already live on a network.
