Free MCP for Google Ads (PaidSync 15 Calls/Month, No Card)

Published May 22, 2026 by Ahmed Ashraf · Founder, PaidSync.ai

PaidSync is the only MCP server for Google Ads that offers a free tier with write access. 15 tool calls per month, no credit card required. Every other option in this category either charges from day one (Ryze AI), limits you to read-only access (Flyweel free tier), or offers fewer than 5 tools (Google's official MCP). This guide compares all four options and shows exactly how to start managing Google Ads with Claude or ChatGPT at zero cost.

The "free MCP for Google Ads" search has grown as AI assistants become standard tools for PPC managers. The options differ in ways that matter significantly, specifically on the question of whether free means full access or just a limited preview of reporting data.

Free MCP options for Google Ads, compared

Why the write access gap matters

A reporting-only MCP lets Claude tell you what is wrong. PaidSync's free tier lets Claude fix what is wrong, within your 15-call monthly budget. The practical difference shows up in how a session ends.

With a read-only MCP, a typical workflow is: ask Claude for wasted spend data, receive the analysis, write down the terms to block, open Google Ads, navigate to the negative keywords section, add them manually. Three to four manual steps remain after the AI conversation ends.

With PaidSync's free tier, that workflow ends in the same conversation. Claude identifies the wasted terms, proposes the negative keyword list, shows you the campaign and ad group scope, and waits for your approval. One click adds them. The AI conversation is the work, not a research step that precedes the work.

What Google's official MCP actually covers

Google maintains an open-source Google Ads MCP in a public GitHub repository. It is genuinely free and connects to the Google Ads API. The tool count is approximately 3: get_campaigns, get_ad_groups, and get_keywords. These three read operations cover basic data retrieval but nothing else.

You cannot create a campaign, adjust a bid, apply negative keywords, generate a wasted spend report, access Performance Max data, or run any analysis beyond raw object retrieval. For teams experimenting with AI and Google Ads connectivity at the most basic level, the official MCP is a starting point. For any operational work, 3 read-only tools are not enough.

Flyweel's free tier

Flyweel offers a free tier with reporting access. You can pull campaign performance, ad group data, and keyword metrics into Claude or ChatGPT. The free tier does not include write access. You can analyze but not act. For advertisers who want performance data in their AI conversations without execution capability, Flyweel's free tier works. For advertisers who want the full loop, it stops halfway.

Ryze AI pricing

Ryze AI has no free tier. It is an autonomous optimization platform that adjusts bids and budgets on a continuous schedule without per-action approval. Third-party comparisons place Ryze pricing between $100 and $500 per month depending on managed ad spend. If you want to evaluate an AI tool for Google Ads without a financial commitment, Ryze is not a free-tier option.

How to start with PaidSync's free tier

The setup takes under two minutes from sign-up to first tool call.

What 15 free calls can accomplish

The 15-call limit is a real constraint. Planning sessions around it makes the difference between a useful month and running out before you accomplish anything.

High-value uses of 15 monthly calls:

• One full wasted spend audit with negative keyword application (4-6 calls). Find the top 20 wasted-spend terms, review the proposed negatives, apply to relevant campaigns and ad groups.
• One campaign performance review with bid adjustment (5-7 calls). Pull keyword-level performance for one campaign, identify underperformers, propose bid changes, apply the approved changes.
• One search term n-gram analysis (3-5 calls). Run analyze_search_term_ngrams to find recurring low-quality patterns, then add them as phrase or broad match negatives at the campaign level.

Lower-value uses that burn calls without proportional return: pulling the same report multiple times, running exploratory queries without a clear action goal, checking account context repeatedly in the same session.

Real workflow examples on the free tier

Audit and block wasted spend

Prompt: "Pull the wasted spend report for my Search campaigns over the last 60 days. Show me terms with more than $50 spend and zero conversions, sorted by spend."

PaidSync returns a table of search terms with cost, clicks, impressions, and the campaign and ad group they matched to. You review the list, confirm the terms you want to block, and ask Claude to apply them as campaign-level negatives. Two to three tool calls. Done.

Adjust keyword bids by position

Prompt: "Show me keywords in my Brand campaign with average position below 3 and CPC over $2. I want to reduce bids on any that have a ROAS below 2."

Claude pulls keyword-level data, filters to your criteria, and proposes specific bid reductions. You review and approve. PaidSync applies the changes. Two to four tool calls depending on the campaign size.

Check Quality Score distribution

Prompt: "Pull Quality Score distribution for my top 3 campaigns by spend. Flag any keywords with QS below 5."

One tool call for the data. Claude presents the distribution and highlights underperformers. No write action needed unless you choose to pause low-QS keywords, which adds one more call.

Upgrading beyond the free tier

When 15 calls per month is not enough, PaidSync Plus at $49/month gives you 150 calls, Pro at $99/month gives you 600, and Max at $199/month gives you 4,000. All paid tiers include the full 309-tool stack across all 8 platforms: Google Ads, Meta Ads, LinkedIn Ads, TikTok Ads, GTM, GA4, Google Search Console, and Google Merchant Center.
