The Docweave PDF MCP server implements two focused, well-named tools with comprehensive Zod-based schemas and detailed descriptions. Both tools follow verb_noun naming convention (generate_pdf, read_pdf), have full input schemas with type definitions and per-parameter descriptions, and return structured results. Tool descriptions are 200+ characters and explain the canonical use case. However, output schemas are not explicitly documented in the visible code (they are inferred from implementation), and the server lacks explicit error recovery guidance patterns. Parameter descriptions are thorough and include constraints and format hints. The schemas use Zod with excellent description chaining, meeting the 100% A+ baseline for schema presence. No critical security issues detected, the server properly handles file paths, validates source types, and uses error responses rather than surfacing internal details.

• Document output schemas explicitly in the tool registration. For generate_pdf, document that successful responses return {content: [{type: 'text', text: '<path or base64>'}]}. For read_pdf, document {content: [{type: 'text', text: '<header>'}, {type: 'text', text: '<content>'}]}.
• Enhance error messages with recovery guidance. E.g., for read_pdf path failures: 'Invalid file path "<path>". Ensure it is absolute and the file exists. Alternatively, provide the PDF as base64 or a public URL.'
• Add per-variant validation for mutually exclusive source fields. If source.type='html' but html field is empty or null, return 'generate_pdf: source.html is required when type is "html". Provide HTML content as a non-empty string.'
• Consider adding a dry-run or preview mode for generate_pdf to support confirmation workflows, per pattern:confirmation-request. E.g., 'preview=true' returns metadata (estimated page count, file size) without writing.
