Summary

The server defines three Kubernetes read-only tools with basic FastMCP registration. Tool names follow verb_noun convention (get-pods, get-namespaces, check-logs) and are reasonably clear. However, there are significant gaps in schema completeness, parameter descriptions are minimal, and output structures are not formally documented. All tools are READ_ONLY and lack error recovery guidance. The implementation wraps Kubernetes API calls but does not provide structured schemas for LLM consumption or actionable error messages.

Tools (3)

check-logsread onlysource verified58/100

Get logs from a specific pod.

get-namespacesread onlysource verified55/100

Get list of all namespaces in the cluster.

get-podsread onlysource verified63/100

Get list of pods in a specified namespace.

Issues (6)

HIGHtool ↗

Output schemas not documented. Tools return dict with 'content' and optional metadata fields, but LLMs cannot infer the structure of 'pods', 'namespaces', or log text responses. No formal schema definition visible in code.

HIGHconstrained-input ↗

Parameter descriptions lack format constraints and ranges. 'namespace' param is described as 'Kubernetes namespace (default: "default")' but does not specify format (alphanumeric, length limits, or regex pattern). 'tail_lines' accepts integer but no min/max bounds documented.

HIGHrecovery-guide ↗

Error handling returns generic exception messages ('Error getting pods: ...') without recovery guidance. LLMs cannot determine if errors are retryable, user-fixable, or fatal. Missing 'try search_namespaces() first' or 'check if namespace exists' hints.

Recommendations

Document the output schema for each tool. Example for get-pods: 'Returns {"pods": [{"name": string, "namespace": string, "status": string, "node": string, "ip": string, "containers": [string]}], "total": integer}'.
Add format constraints to parameter descriptions. For namespace: 'Kubernetes namespace name (alphanumeric and hyphens, 3-63 characters, default: "default")'. For tail_lines: 'Number of lines (1-10000, default: 100)'.
Implement pagination for get-pods and get-namespaces. Add 'limit' (default 50, max 500) and 'offset' (default 0) parameters. Return 'total_count' and 'has_more' fields to support multi-page queries.
Enhance error messages with recovery guidance. Replace 'Error getting pods: {exception}' with 'Pod not found in namespace "X". Valid namespaces: {list}. Call get-namespaces() to list all available namespaces.'
Clarify tool selection criteria in descriptions. Example: 'Use get-pods to discover pods in a namespace; use check-logs to debug a specific pod. Always call get-pods first if you do not know the pod name.'
Validate input parameters and return clear validation errors. If namespace does not exist, return 'Invalid namespace: "xyz" not found. Available namespaces: [list].' This enables LLM self-correction.
Add tool annotations (readOnlyHint) to signal idempotency and safety. All three tools are read-only and safe to retry, declare this for LLM reasoning.
Consider batch variants: add get_pods_across_namespaces to fetch pods from multiple namespaces in one call, reducing context overhead.
