## Installation
1. First, download and install the latest release from the [releases page](https://github.com/mozillazg/kube-audit-mcp/releases).
* You can also install via docker:
```bash
docker pull quay.io/mozillazg/kube-audit-mcp:latest
```
2. Then, configure the provider of Kubernetes Audit Logs. See [Configurations](#configurations) for details.
## MCP Clients
Theoretically, any MCP client should work with kube-audit-mcp.
**Standard config** works in most of the clients:
```json
{
"mcpServers": {
"kube-audit": {
"type": "stdio",
"command": "kube-audit-mcp",
"args": [
"mcp"
]
}
}
}
```
Run with docker
You can also run kube-audit-mcp via docker, use the following config:
```json
{
"mcpServers": {
"kube-audit": {
"type": "stdio",
"command": "docker",
"args": [
"run",
"-i",
"--rm",
"-v",
"/etc/kube-audit-mcp/config.yaml:/etc/kube-audit-mcp/config.yaml:ro",
"quay.io/mozillazg/kube-audit-mcp:latest",
"mcp",
"--config",
"/etc/kube-audit-mcp/config.yaml"
],
"env": {
"ALIBABA_CLOUD_ACCESS_KEY_ID": "needed_if_you_use_alibaba_sls_provider",
"ALIBABA_CLOUD_ACCESS_KEY_SECRET": "needed_if_you_use_alibaba_sls_provider",
"AWS_ACCESS_KEY_ID": "needed_if_you_use_aws_cloudwatch_logs_provider",
"AWS_SECRET_ACCESS_KEY": "needed_if_you_use_aws_cloudwatch_logs_provider",
"GOOGLE_APPLICATION_CREDENTIALS": "needed_if_you_use_gcp_cloud_logging_provider"
}
}
}
}
```
### Claude Code
Use the Claude Code CLI to add the kube-audit-mcp:
```
claude mcp add kube-audit kube-audit-mcp mcp
```
### Claude Desktop
Follow the MCP install [guide](https://modelcontextprotocol.io/quickstart/user), use the standard config above.
### Gemini CLI
Follow the MCP install [guide](https://github.com/google-gemini/gemini-cli/blob/main/docs/tools/mcp-server.md#configure-the-mcp-server-in-settingsjson),
use the standard config above.
### VS Code
Follow the MCP install [guide](https://code.visualstudio.com/docs/copilot/chat/mcp-servers#_add-an-mcp-server),
use the standard config above. You can also install the kube-audit-mcp MCP server using the VS Code CLI:
```bash
# For VS Code
code --add-mcp '''{"name":"kube-audit","command":"kube-audit-mcp","args":["mcp"]}'''
```
After installation, the kube-audit-mcp MCP server will be available for use with your GitHub Copilot agent in VS Code.
### kubectl-ai
Follow the MCP install [guide](https://github.com/GoogleCloudPlatform/kubectl-ai/blob/main/pkg/mcp/README.md#local-stdio-based-server-configuration),
use the config like below:
```yaml
servers:
# Local MCP server (stdio-based)
- name: kube-audit
command: kube-audit-mcp
args:
- mcp
```
## Transport Options
### STDIO Transport (Default)
The default transport mode uses standard input/output for communication.
This is the standard MCP transport used by most clients like Claude Desktop.
```
# Run with default stdio transport
kube-audit-mcp mcp
# Or explicitly specify stdio
kube-audit-mcp mcp --transport stdio
```
## Configurations
kube-audit-mcp requires a configuration file to specify the provider of Kubernetes Audit Logs.
The configuration file is typically located at `~/.config/kube-audit-mcp/config.yaml`
or specified via the `--config` flag.
### Sample Config
You can get a sample config via the following command:
```
kube-audit-mcp sample-config
```
Here is a sample configuration file
```yaml
default_cluster: prod # The default cluster to use
clusters: # List of clusters
- name: prod # Name of the cluster
provider: # Provider configuration, see below for details
name: aws-cloudwatch-logs # Use CloudWatch Logs as the provider
aws_cloudwatch_logs:
log_group_name: /aws/eks/test/cluster # Replace with your CloudWatch Logs log group name
- name: dev # Name of the cluster
provider:
name: alibaba-sls # Use Alibaba Cloud Log Service as the provider
alibaba_sls:
endpoint: cn-hangzhou.log.aliyuncs.com # Replace with your Log Service endpoint
project: k8s-log-cxxx # Replace with your Log Service project
logstore: audit-cxxx # Replace with your Log Service logstore
- name: test
provider:
name: gcp-cloud-logging # Use Google Cloud Logging as the provider
gcp_cloud_logging:
project_id: test-233xxx # Replace with your Project ID
cluster_name: test-cluster # Replace with your GKE cluster name (optional)
```
Or save the sample configuration to the default config file location:
```
kube-audit-mcp sample-config --save
```
### Provider
#### Alibaba Cloud Log Service
Prerequisites:
* [Install and configure the Alibaba Cloud CLI with credentials](https://www.alibabacloud.com/help/en/cli/configure-credentials)

## Available Tools
This MCP server exposes the following tools to the AI agent:
### `query_audit_log`
Queries the Kubernetes audit logs from the configured provider. This is the primary tool for investigating activity in your clusters.
**Parameters:**
* `cluster_name` (string, optional): The name of the cluster to query. You can see available clusters with the `list_clusters` tool. Defaults to the configured `default_cluster`.
* `start_time` (string, optional): The start time for the query. Can be in ISO 8601 format (`2024-01-01T10:00:00`) or relative time (`7d`, `1h`, `30m`). Defaults to `7d`.
* `end_time` (string, optional): The end time for the query. If omitted, defaults to the current time.
* `limit` (number, optional): The maximum number of log entries to return. Defaults to `10`, with a maximum of `20`.
* `namespace` (string, optional): Filter logs by a specific namespace. Supports suffix wildcards (e.g., `kube-*`).
* `resource_types` (array of strings, optional): Filter by one or more Kubernetes resource types (e.g., `pods`, `deployments`). Supports short names (e.g., `po`, `deploy`). Use `list_common_resource_types` to discover available types.
* `resource_name` (string, optional): Filter by a specific resource name. Supports suffix wildcards.
* `verbs` (array of strings, optional): Filter by one or more action verbs (e.g., `create`, `delete`, `update`).
* `user` (string, optional): Filter by the user who performed the action. Supports suffix wildcards.
### `list_clusters`
Lists all clusters that are configured in the `config.yaml` file. This is useful for discovering which clusters you can target for queries.
**Parameters:** None
### `list_common_resource_types`
Returns a list of common Kubernetes resource types, grouped by category (e.g., "Core Resources", "Apps Resources"). This helps in finding the correct value for the `resource_types` parameter in the `query_audit_log` tool.
**Parameters:** None
