The server exposes a single tool, KBPublisher, with a WRITE risk profile. While the tool has a basic description and visible input schema, the implementation lacks critical production-grade patterns: no output schema documentation, no error handling guidance, no parameter validation constraints, and the schema is inferred from source rather than formally registered. The description is adequate but generic (117 chars), and parameter descriptions are minimal to absent. No evidence of idempotency, dry-run, or confirmation patterns for this destructive operation. The server does not follow verb_noun naming ('KBPublisher' is a noun-focused class name, not an action verb like 'create_kb_article' or 'publish_kb_article'). Parameter 'meta' is vaguely typed as 'object' with no constraints. No evidence of rate limiting, permission gating, or audit trail support. The codebase shows Streamlit-based token resolution and health-check infrastructure, but no actual tool registration endpoint or MCP manifest visible.

• Rename 'KBPublisher' to 'create_kb_article' or 'update_kb_article' (use verb_noun pattern). Start the name with an action verb so LLMs can infer intent from the name alone.
• Document the complete output schema. Specify what fields are returned on success (e.g., { "article_id": string, "url": string, "created_at": ISO8601, "status": string }). Ensure article_id is included so agents can chain to other operations.
• Add an explicit 'operation' parameter with enum values ['create', 'update'] instead of inferring from context. This reduces ambiguity.
• Expand 'audience' description with valid enum values: ['All', 'Internal', 'External', 'Restricted', ...]. Document any ServiceNow-specific audience codes.
• Define 'meta' parameter more precisely. Either enumerate known metadata fields or document the schema (e.g., { "category": string, "severity": enum, "owner_group": string }). Validate against schema server-side.
• Add error handling examples: 'If authentication fails (401), check SERVICENOW_API_KEY in secrets. If quota exceeded (429), retry after 60 seconds. If HTML invalid, return 400 with line number of malformed tag.'
• Implement permission checking: verify the calling agent/user has 'write:kb' scope before executing. Return 403 'Insufficient permissions' if not authorized.
• Create a proper MCP manifest.json that registers this tool with the full schema. Expose via an HTTP endpoint (/tools or /mcp/tools) so clients can discover it.
• Add a 'dry_run' boolean parameter (default false) to support confirmation patterns. When true, validate inputs and return expected output without modifying ServiceNow.
