This MCP server exhibits severe quality issues across the definition dimension. While all 10 tools have names and basic descriptions, the implementation lacks critical requirements: (1) Most parameter descriptions are generic or missing context. (2) Output schemas are not documented anywhere in the provided source. (3) No input validation or error recovery guidance. (4) Parameters lack type constraints (enums, ranges, format specs). (5) Several tools expose sensitive configuration (certificates, passwords) as parameters rather than injecting them server-side. The server appears to be a STDIO-only implementation, which is a hard transport cap. Beyond naming conventions (which are reasonable: pje_configurar, pje_listar_processos), the definitions are minimal and do not meet production-grade standards.

• Move 'pfxPassword' and 'certificatePassword' out of pje_configurar_certificado parameters. Inject them from environment variables (e.g., process.env.PJE_CERTIFICATE_PASSWORD) so they never appear in tool signatures or traces.
• Document output schemas for all tools. For list tools, specify: returned fields (id, name, status, etc.), total count, pagination fields. Example: pje_listar_processos should return {processos: [{id, numero, status, data_abertura, ...}], total, page, size}.
• Expand parameter descriptions to 50 - 100 characters and include: WHAT the parameter does, VALID values or constraints, FORMAT/PATTERN if applicable, EXAMPLE if helpful. E.g., 'filter: Search expression for process number or party name. Format: free text or regex. Example: "2024.*civil".'
• Add min/max bounds to numeric parameters. E.g., 'page: Page number (1-based, default 1)'; 'size: Items per page (1 - 100, default 20)'.
• For list tools, add guidance on pagination. E.g., pje_listar_processos description should say: 'Returns up to <size> processes. Use page parameter to iterate. Total count included in response.'
• Add error recovery hints to descriptions. E.g., pje_buscar_processo: 'If process not found, call pje_listar_processos() with a filter to search by partial match.'
• For pje_configurar_certificado, add output schema and document certificate validation. Return: {thumbprint, subject, issuer, validFrom, validTo, status: 'valid'|'expired'|'invalid'}.
• Add tool annotations (readOnlyHint, destructiveHint, idempotentHint) to clarify side effects. E.g., pje_configurar and pje_configurar_certificado should have destructiveHint: true if they overwrite previous config.
