AI Analysis

●MidShip ItNiche Gem

Yet another MCP wrapper, but at least the OpenAI Ads API is genuinely new.

Strengths
  • •Zero-install via npx means no cloning repos or building from source
  • •Returns API JSON faithfully without losing data in translation
  • •Covers 11 read endpoints across accounts, campaigns, ads, and insights
Weaknesses
  • •Read-only for now, can't actually manage or modify campaigns
  • •Extremely narrow audience limited to OpenAI Ads users specifically

Post Description

I built a small MCP server for the ChatGPT Ads advertiser API, which OpenAI opened to the public a couple of weeks ago.

It's read-only for now: accounts, campaigns, ad groups, ads and insights (11 tools in total). You can query campaigns from Claude, Codex, Cursor and so on in plain language. Writes ("actions") are next; I have two ideas here: - wrap them in a deterministic tool (json in/out) - add a human in the loop (maybe even a verification/consistency check step between query and tool/json output)

Claude Code did most of the work but it wasn't a one-shot. The OpenAI API spec is very clean though and easy to understand; for some reason Claude couldn't read OpenAI's own docs, so I ended up with some manual "copy&paste".

Also I iterated a bit and went from a local stdio install to npm and then made it available in the MCP registry.

Feedback welcome, especially on the write/elicitation side and on hosting a remote version.

PS: It's (obviously) unofficial and not affiliated with OpenAI.
