Search for a Google Ads or Search Console MCP server and Composio comes up early, with good reason: its toolkits are broad, its OAuth handling is solid, and it has a free tier. It is also built for a specific user, a developer wiring tools into an agent. Here is what that means once the people in the chat are a marketing team.
What Composio offers for Google
The Google Ads toolkit has 36 tools, and 25 of them write: mutating campaigns, campaign budgets, bidding strategies, ad groups, batch operations. The Search Console toolkit has nine, including Add Site, Delete Site and Submit Sitemap. You can use Composio's managed OAuth app or bring your own, and connect several Google accounts per user. Pricing starts with a free tier of 100,000 tool calls a month, with a lower cap for managed apps, then $29 a month plus usage.
For a developer building an agent product, that is a strong offer. You get every endpoint you might need, handled auth, and you write the policy that fits your product.
Where a marketing team feels the difference
The policy is yours to write
A toolkit exposes what the API can do, and the API can do a lot. Composio's MCP Gateway lets you set action-level rules by organization, team, user or toolkit, so the controls exist. But somebody has to decide that the content team gets reports and no mutate tools, that nobody can delete a Search Console property from a chat, and that a budget change needs a specific role, and then configure it. With 25 write tools for Ads alone, the safe configuration is a project of its own.
Writes can make ads serve
A generic campaign mutate can set a status to enabled. That is not a flaw in Composio, it is what the endpoint does. It means the guardrail is whatever your agent or your chat client puts in front of the call. We wrote about why the chat's confirm button is not enough for that.
The search terms go to the model
Search Console's QUERY dimension contains what real people typed into Google. A toolkit returns what the API returns. Composio states that tool-call payloads are not stored, which is good for what happens afterwards, but the model has already seen them. Holding the terms back before they reach the model is not something the toolkit does for you.
Where it runs
Composio is a US company, and its pages name Composio Cloud, your own VPC or self-hosting for the MCP Gateway. For a German or EU marketing team handing over client accounts, that is a question for the data processing agreement, not a deal breaker.

Which one fits
Building an agent into your own product, with your own policy code: Composio. A team that wants Google Ads and Search Console in the Claude or ChatGPT it already uses, with safe defaults it does not have to design: that is what we built.
