Tools

- deploy-file-contents: Deploys files to Cloud Run by providing their contents directly.
- list-services: Lists Cloud Run services in a given project and region.
- get-service: Gets details for a specific Cloud Run service.
- get-service-log: Gets Logs and Error Messages for a specific Cloud Run service.

- deploy-local-folder\*: Deploys a local folder to a Google Cloud Run service.
- list-projects\*: Lists available GCP projects.
- create-project\*: Creates a new GCP project and attach it to the first available billing account. A project ID can be optionally specified.

_\* only available when running locally_

Prompts

Prompts are natural language commands that can be used to perform common tasks. They are shortcuts for executing tool calls with pre-filled arguments.

- deploy: Deploys the current working directory to Cloud Run. If a service name is not provided, it will use the DEFAULT_SERVICE_NAME environment variable, or the name of the current working directory.
- logs: Gets the logs for a Cloud Run service. If a service name is not provided, it will use the DEFAULT_SERVICE_NAME environment variable, or the name of the current working directory.

Environment Variables

The Cloud Run MCP server can be configured using the following environment variables:

| Variable | Description |
| :----------------------- | :--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| GOOGLE_CLOUD_PROJECT | The default project ID to use for Cloud Run services. |
| GOOGLE_CLOUD_REGION | The default region to use for Cloud Run services. |
| DEFAULT_SERVICE_NAME | The default service name to use for Cloud Run services. |
| SKIP_IAM_CHECK | Controls whether to check for IAM permissions for a Cloud Run service. Set to false to enable checks. This is true by default which is a recommended way to make the service public. |
| ENABLE_HOST_VALIDATION | Prevents DNS Rebinding attacks by validating the Host header. This is disabled by default. |
| ALLOWED_HOSTS | Comma-separated list of allowed Host headers (if host validation is enabled). The default value is localhost,127.0.0.1,::1. |

Use as a Gemini CLI extension

To install this as a Gemini CLI extension, run the following command:

2. Install the extension:

`bash
gemini extensions install https://github.com/GoogleCloudPlatform/cloud-run-mcp
`

3. Log in to your Google Cloud account using the command:

`bash
gcloud auth login
`

4. Set up application credentials using the command:
`bash
gcloud auth application-default login
`

Use in MCP Clients

$3

Most MCP clients require a configuration file to be created or modified to add the MCP server.

The configuration file syntax can be different across clients. Please refer to the following links for the latest expected syntax:

- Antigravity
- Windsurf
- VSCode
- Claude Desktop
- Cursor

Once you have identified how to configure your MCP client, select one of these two options to set up the MCP server.
We recommend setting up as a local MCP server using Node.js.

$3

Run the Cloud Run MCP server on your local machine using local Google Cloud credentials. This is best if you are using an AI-assisted IDE (e.g. Cursor) or a desktop AI application (e.g. Claude).

1. Install the Google Cloud SDK and authenticate with your Google account.

2. Log in to your Google Cloud account using the command:

`bash
gcloud auth login
`

3. Set up application credentials using the command:
`bash
gcloud auth application-default login
`

Then configure the MCP server using either Node.js or Docker:

#### Using Node.js

0. Install Node.js (LTS version recommended).

1. Update the MCP configuration file of your MCP client with the following:

`json
"cloud-run": {
"command": "npx",
"args": ["-y", "@google-cloud/cloud-run-mcp"]
}
`

2. [Optional] Add default configurations

`json
"cloud-run": {
"command": "npx",
"args": ["-y", "@google-cloud/cloud-run-mcp"],
"env": {
"GOOGLE_CLOUD_PROJECT": "PROJECT_NAME",
"GOOGLE_CLOUD_REGION": "PROJECT_REGION",
"DEFAULT_SERVICE_NAME": "SERVICE_NAME"
}
}
`

#### Using Docker

See Docker's MCP catalog, or use these manual instructions:

0. Install Docker

1. Update the MCP configuration file of your MCP client with the following:

`json
"cloud-run": {
"command": "docker",
"args": [
"run",
"-i",
"--rm",
"-e",
"GOOGLE_APPLICATION_CREDENTIALS",
"-v",
"/local-directory:/local-directory",
"mcp/cloud-run-mcp:latest"
],
"env": {
"GOOGLE_APPLICATION_CREDENTIALS": "/Users/slim/.config/gcloud/application_default-credentials.json",
"DEFAULT_SERVICE_NAME": "SERVICE_NAME"
}
}
`

$3

> [!WARNING]
> Do not use the remote MCP server without authentication. In the following instructions, we will use IAM authentication to secure the connection to the MCP server from your local machine. This is important to prevent unauthorized access to your Google Cloud resources.

Run the Cloud Run MCP server itself on Cloud Run with connection from your local machine authenticated via IAM.
With this option, you will only be able to deploy code to the same Google Cloud project as where the MCP server is running.

1. Install the Google Cloud SDK and authenticate with your Google account.

2. Log in to your Google Cloud account using the command:

`bash
gcloud auth login
`

3. Set your Google Cloud project ID using the command:
`bash
gcloud config set project YOUR_PROJECT_ID
`
4. Deploy the Cloud Run MCP server to Cloud Run:

`bash
gcloud run deploy cloud-run-mcp --image us-docker.pkg.dev/cloudrun/container/mcp --no-allow-unauthenticated
`

When prompted, pick a region, for example europe-west1.

Note that the MCP server is _not_ publicly accessible, it requires authentication via IAM.

5. [Optional] Add default configurations

`bash
gcloud run services update cloud-run-mcp --region=REGION --update-env-vars GOOGLE_CLOUD_PROJECT=PROJECT_NAME,GOOGLE_CLOUD_REGION=PROJECT_REGION,DEFAULT_SERVICE_NAME=SERVICE_NAME,SKIP_IAM_CHECK=false
`

6. Run a Cloud Run proxy on your local machine to connect securely using your identity to the remote MCP server running on Cloud Run:

`bash
gcloud run services proxy cloud-run-mcp --port=3000 --region=REGION --project=PROJECT_ID
`

This will create a local proxy on port 3000 that forwards requests to the remote MCP server and injects your identity.

7. Update the MCP configuration file of your MCP client with the following:

`json
"cloud-run": {
"url": "http://localhost:3000/sse"
}

`

If your MCP client does not support the url attribute, you can use mcp-remote:

`json
"cloud-run": {
"command": "npx",
"args": ["-y", "mcp-remote", "http://localhost:3000/sse"]
}
