Google Ads performance audit — Monthly audit that surfaces underperformers and points you at the quick wins.

Overview

Adspirer is the MCP server that connects OpenAI Codex CLI to your Google Ads ad accounts, turning campaign management into a chat conversation. OpenAI's Codex CLI — script-friendly agent loop with MCP support. On the platform side, 39 tools cover google Search, Performance Max, Display, YouTube, Shopping. Adspirer reads and writes — pull performance reports, audit launch search & pmax campaigns, launch new campaigns, pause underperformers, and reallocate budget — all from chat. New campaigns are always created paused so you can review before they go live, Adspirer cannot delete existing campaigns by design, and the free tier (15 tool calls / month, no credit card) is enough to run a full audit before you pay. Setup takes about 5 minutes via a JSON config entry.

Safety guarantees

New campaigns always created paused for review

What you can do

39 tools across Google Ads. The ones you'll use most:

Launch Search & PMax campaigns — Build Google Search and Performance Max campaigns from a brief — Adspirer runs keyword research, drafts copy, validates assets, and creates the campaign **paused** so you review before going live.
Research keywords with real CPC — Pull live data from Google Keyword Planner via `research_keywords` — search volume, CPC estimates, and competition level for any seed keyword or business description.
Find wasted spend — Run `analyze_wasted_spend` to surface keywords that have spent your threshold (e.g., $50+) with zero conversions, then pause them or push them to negatives in one prompt.
Audit search terms — Use `analyze_search_terms` to see the actual queries that triggered your ads. The `raw_report` mode returns the literal search strings — perfect for finding negative-keyword opportunities.
Generate ad copy in-spec — `suggest_ad_content` writes headlines (≤30 chars) and descriptions (≤90 chars) that fit Google's exact limits, so RSAs never get rejected for length.
Pause & resume campaigns — Pause campaigns, ad groups, or keywords by name from chat — and resume them later. Adspirer **cannot delete** existing campaigns by design (hard-coded safety).
Tune PMax targeting — Add or remove search themes (up to 50 per asset group) and audience signals (in-market, affinity, custom, user lists) on existing PMax campaigns — without rebuilding from scratch.
Reallocate budget by ROAS — `optimize_budget_allocation` recommends shifts toward your best-ROAS campaigns. Adspirer never raises an existing campaign budget without your explicit confirmation.

More prompts to try

Codex handles long-running agent loops; brief it like you would Claude Code.

Diagnose a CPA spike — Anomaly diagnosis that explains why CPA moved, not just that it did.

Diagnose a CPA spike

My CPA on the "Adspirer-pmax-03" campaign jumped 60% in the last 7 days. Diagnose what changed — search terms, audience signals, asset rotation — and tell me what to fix.

Who this is for

Each Monday, ask Codex CLI to pull last week's Google Ads performance, surface campaigns running below your ROAS threshold, and recommend creative refreshes for fatigued ads.

Replaces a 60–90 minute manual review with a 5-minute chat, and surfaces problems before they tank ad-set performance.

FAQ

Setup

Do I need a developer to set this up?

You'll edit a small JSON config entry to register the Adspirer MCP server (https://mcp.adspirer.com/mcp, transport http, OAuth). If you can edit a settings file in a code editor, you can do this. Total time: about 5 minutes.

Capabilities

Can I switch from Codex CLI to a different AI client later?

Yes. Your Adspirer account is independent of the AI client — sign up once, then connect the same MCP URL from ChatGPT, Claude, Cursor, Codex, Windsurf, or any supported client. Tool calls are pooled across clients on the same plan; switching costs you nothing.

What's the minimum budget for Google Ads campaigns?

Search campaigns work from $10/day (Google's practical minimum), but $30+/day is recommended for meaningful data. Performance Max needs at least $20/day because it has to test across multiple channels. Adspirer suggests $40/day split across 3-5 ad groups for new Search campaigns.

How are conversions and search terms surfaced?

Use get_campaign_performance for spend / conversions / CPA / ROAS by campaign, and analyze_search_terms to see the actual queries that triggered your ads. The raw_report mode returns the literal search-term strings — feed those into add_negative_keywords to block wasteful traffic in the next prompt.

Workflows

Does Adspirer generate images or videos for Google Ads?

No. Adspirer generates ad copy (headlines and descriptions) via suggest_ad_content, but it does not create images or videos. For PMax, you provide image and video URLs from Google Drive, Dropbox, S3, or any public link, and validate_and_prepare_assets checks them against Google's spec before launch.

How does the campaign-creation workflow work?

Search campaigns require a 6-step sequence: verify connection → research_keywords → discover_existing_assets → suggest_ad_content → validate_and_prepare_assets → create_search_campaign. PMax adds asset upload guidance plus optional add_pmax_search_themes and add_pmax_audience_signal. Skipping steps causes Google's API to reject the campaign — Adspirer enforces the order.

Compare

What's the read vs. write boundary on Google Ads?

Adspirer is full read and write. It can pull reports, audit performance, and analyze data (read), and it can launch new campaigns, pause underperformers, update budgets, and adjust targeting (write). Two safety guardrails are hard-coded: new campaigns are always created paused so you review before they go live, and Adspirer cannot delete existing campaigns. You keep full control.

Safety & control

Can Adspirer delete or modify my existing campaigns?

Adspirer cannot delete campaigns, ad groups, or keywords — hard-coded safety. It can pause and resume them when you ask, and update budgets, bids, or targeting on your instruction. New campaigns are always created paused so you review before they spend a cent.

Power user

Can I manage multiple Google Ads accounts (MCC) from one chat?

Yes. Connect each ad account through OAuth and Adspirer keeps them separate. Use get_connections_status to list connected accounts and reference them by customer ID or name in your prompts. Adspirer's own workspace, for example, has both Adspirer (9120801776) and Sahaayak Inc (1187072345) connected side-by-side.
