工具

该 MCP 服务器提供以下工具用于与证书管理器和 Kubernetes 资源交互：

证书管理

• list_certificates - 在命名空间内或所有命名空间中列出证书，并提供过滤过期证书和分页选项。你还可以为列出的证书添加域，参数include_domains（默认为 False 以便响应更简洁）
• get_certificate - 获取特定证书的详细信息
• renew_certificate - 强制续期证书

发行人管理

• list_issuers - 列出发行者或集群发行者及其状态和配置。与list_certificates不同，除集群/命名空格发行者和发行者命名空间外，没有分页或过滤。

Kubernetes 上下文管理

• list_namespaces - 列出簇中的所有命名空间
• list_contexts - 列出所有可用的 kubeconfig 上下文

Tools

This MCP server provides the following tools for interacting with cert-manager and Kubernetes resources:

Certificate Management

• list_certificates - List certificates within a namespace or across all namespaces, with options for filtering expired certificates and pagination. You can also include domains for listed certificates with include_domains argument (defaults to False to make responses more compact)
• get_certificate - Get detailed information about a specific certificate
• renew_certificate - Force renewal of a certificate

Issuer Management

• list_issuers - List issuers or cluster issuers with their statuses and configuration. Unlike list_certificates there are no pagination or filtering except for cluster/namespaced issuers and namespaces for Issuers.

Kubernetes Context Management

• list_namespaces - List all namespaces in the cluster
• list_contexts - List all available kubeconfig contexts
• get_current_context - Get the currently active kubeconfig context
• switch_context - Switch to a different kubeconfig context. Updates in-memory config
