Why this level
- Plugins connect the agent to live Google Cloud databases where it can read and change data.
- Database content can carry instructions for the model, so permissions are limited through a service account.

What it does
This Google Cloud repository is a showcase of data extensions. One marketplace connects to Claude Code or Codex, while Gemini CLI and Antigravity CLI install plugins straight from repositories. Inside are plugins for AlloyDB, three flavours of Cloud SQL, Spanner, Bigtable, Firestore, Looker, Oracle Database, Google Cloud Storage and Knowledge Catalog. Each plugin packages skills and MCP servers for its product, so an agent creates databases, connects to them and works with data through ordinary requests. A separate Data Agent Kit helps build pipelines in BigQuery, Dataflow and Spark. The repository also holds an MCP server guide plus examples of agent analytics and evaluation on BigQuery.
Who it is for. Data engineers and developers on Google Cloud who want to handle databases and pipelines through Claude Code, Codex or Gemini CLI.
Good fit when
- The project runs on Spanner or AlloyDB and the agent must write queries against a real database.
- A pipeline in BigQuery and Dataflow with dbt transformations has to be set up.
- A team picks official Google Cloud plugins from one marketplace instead of hunting repositories.
- You are building your own agent and need analytics and evaluation examples on BigQuery.
Not a fit when
- The data sits outside Google Cloud and the product you need is not on the list.
- You want one plugin with ready logic: this is an index, and the plugins live in separate repositories.
- Production databases cannot be exposed to an agent even through a service account.
Example request
Connect to the Spanner database of my project, show the orders table schema and write a query for weekly order totals.Limitations
This is an index: product plugins live in separate repositories and join as submodules, so check their requirements there. The agent works with your cloud resources and can change data. The authors ask for service accounts with minimal roles and principal access boundaries instead of personal credentials. Prompt injection through database content remains a risk, and Google documents it on a separate page. For Oracle Database the table lists Gemini CLI only.
How to disable. Remove the plugins and the marketplace itself with the plugin manager of your agent. Revoke the service account permissions separately in Google Cloud.
FAQ
How do I install the plugins in Claude Code?
Run `claude plugin marketplace add GoogleCloudPlatform/data-cloud-plugins`, then in a session `/plugin install <name>@data-cloud-plugins` and `/reload-plugins`. Update the marketplace with `claude plugin marketplace update data-cloud-plugins`.
How do I install a plugin in Codex?
Add the marketplace with `codex plugin marketplace add GoogleCloudPlatform/data-cloud-plugins`, then install a plugin with `codex plugin add <name>@data-cloud-plugins`.
What about Gemini CLI?
The extension installs from the product repository: `gemini extensions install https://github.com/GoogleCloudPlatform/<REPO>`, where `<REPO>` is a repository name from the table.
Which products are covered?
AlloyDB and AlloyDB Omni, Bigtable, three Cloud SQL variants, Firestore, Looker, Oracle Database, Spanner, Google Cloud Storage and Data Agent Kit for BigQuery, Dataflow and Spark.
How do I limit agent permissions?
Work through a service account with limited roles and set up a Principal Access Boundary so the agent cannot leave the intended projects.
