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 trial or subscription (no card required to start)

​
Setup

1

Open the configuration file

Edit ~/.codex/config.toml and add the TryPost server:
[mcp_servers.trypost]
type = "http"
url = "https://app.trypost.it/mcp/trypost"
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 mcp login trypost
Codex opens your browser to TryPost; approve the request and return to the terminal.
3

Verify the connection

Start Codex and ask:
List all my TryPost posts
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.
For headless environments, use a Personal Access Token via environment variable:
export TRYPOST_API_KEY="YOUR_API_KEY"

[mcp_servers.trypost]
type = "http"
url = "https://app.trypost.it/mcp/trypost"
bearer_token_env_var = "TRYPOST_API_KEY"
Create the key from Settings > API Keys on the TryPost dashboard. bearer_token_env_var keeps the token out of the config file.
