Terminal-native OpenAI agent — bridged to your social media until native MCP lands.

Codex CLI is OpenAI's answer to Claude Code: a terminal agent that reads, edits, and executes against your codebase. MCP support is rolling out across OpenAI's CLI products, but at the time of writing the published Codex CLI does not yet match Claude Code's first-class MCP support across all tiers. While that lands, the working pattern is the same shape Cursor and Claude Code use — point Codex CLI at SociaHive's MCP endpoint via its tool-call configuration, or bridge through Zapier for the simplest cases. Same SociaHive API key carries forward when native MCP arrives.

Why pair OpenAI Codex CLI with SociaHive

Today: bridge via Zapier or Codex CLI's tool-call config; tomorrow: native MCP

Native MCP support across OpenAI's CLI surface is rolling out; check the Codex CLI release notes for your tier. While that ships, the most reliable path is the Webhooks by Zapier bridge (same pattern documented for ChatGPT) — Codex CLI calls a Zap, the Zap hits SociaHive, results stream back. The SociaHive side is identical; only the transport differs.

# TODAY — bridge via Webhooks by Zapier
#
# Codex CLI emits a tool call (function_call). Wire the function to a
# Webhook trigger (Zapier or your own HTTP server) that forwards the
# JSON-RPC body to SociaHive's MCP endpoint:
#
#   POST https://sociahive.com/api/mcp
#   Headers: X-API-Key: sk_your_key_here
#            Content-Type: application/json
#   Body:    {
#              "jsonrpc": "2.0",
#              "id": "<correlate to function_call.id>",
#              "method": "tools/call",
#              "params": {"name": "<tool>", "arguments": {...}}
#            }
#
# Codex CLI receives the parsed response back through the same channel
# and treats it as a tool result.

# TOMORROW — native MCP (when OpenAI ships it for your tier)
#
#   In your Codex CLI MCP config:
#     {
#       "mcpServers": {
#         "sociahive": {
#           "url": "https://sociahive.com/api/mcp",
#           "headers": {
#             "X-API-Key": "sk_your_key_here"
#           }
#         }
#       }
#     }
#
# Same SociaHive API key. Drop the Zapier hop. Done.

A real workflow: launch-day campaign from your terminal, bridge-mediated

Same launch-day flow as the Claude Code page, but driven by Codex CLI on GPT-5/o-series with the Zapier bridge in the middle. The agent builds the Instagram + WhatsApp DM flows and schedules the LinkedIn + Twitter announcement; all destructive ops still hit the pending_confirmation gate.

1. 1You drop a launch brief into Codex CLI: 'Set up early-access on @launchaccount. Comment trigger "early" on Instagram, keyword trigger "early" on WhatsApp. Schedule the announcement on LinkedIn and Twitter for 9am tomorrow.'
2. 2Codex CLI emits a sequence of tool calls (or a single batched call, depending on the model). Each call is forwarded to your Zapier bridge or HTTP forwarder, which POSTs the JSON-RPC body to https://sociahive.com/api/mcp.
3. 3SociaHive returns the standard envelope shape — successful results inline, pending_confirmation for the destructive ops (publish_post_now if you asked it to publish-now, or activate_flow if you wanted the DM flow live immediately).
4. 4Codex CLI surfaces the envelopes as tool results; you approve via the dashboard URL each envelope carries, or hand the URLs to a teammate.
5. 5Once OpenAI's native MCP rollout reaches your account, you replace the Zapier bridge with a direct mcpServers entry in Codex CLI's config — same workflow, fewer hops.

# Tools registered via Codex CLI's tool-call config or function_call
# definitions. The bridge forwards each call to SociaHive's MCP endpoint.

> Set up early-access on @launchaccount Instagram + WhatsApp.
> Schedule the announcement on LinkedIn + Twitter for 9am tomorrow.
