MCP for the CLI

Postproxy × Codex

Give the Codex CLI real social publishing. Add Postproxy once and publish, schedule, and manage content across 11 platforms from your terminal.

One entry in `~/.codex/config.toml`, shared by every Codex session, and your agent can publish through Postproxy in plain language.

One config entry

Add Postproxy to ~/.codex/config.toml

Codex launches MCP servers from `config.toml`. Bridge the hosted endpoint with `mcp-remote` and your API key — one entry, backed by our hosted server.

~/.codex/config.toml

[mcp_servers.postproxy]
command = "npx"
args = ["-y", "mcp-remote", "https://mcp.postproxy.dev/mcp?api_key=YOUR_KEY"]

How Postproxy works inside Codex

1

Add the server entry

Append the Postproxy block to `~/.codex/config.toml` and replace `YOUR_KEY` with a key from your dashboard.

2

Restart Codex

Start a new Codex session so it picks up the server; the Postproxy tools become available to the agent.

3

Ask in the terminal

"Publish this to X and LinkedIn." Codex calls the tools and confirms the result.

4

Postproxy executes

We handle platform rules, media, rate limits, and retries, and return per-platform results.
