Claude Writer's Aid MCP

Instructions

Implementation Reference

• src/tools/WriterToolHandlers.ts:425-440 (handler)

  Primary handler function for the 'get_requirements' MCP tool. Parses input arguments and delegates execution to WritersAid.getRequirements().
  private async getRequirements(args: Record<string, unknown>) { const requirementType = args.requirement_type as | "word_count" | "citation_style" | "formatting" | "deadline" | "target_audience" | "tone" | "reading_level" | "chapter_count" | "other" | undefined; const enforcedOnly = args.enforced_only as boolean | undefined; return this.writersAid.getRequirements({ requirementType, enforcedOnly }); }
• src/tools/WriterToolDefinitions.ts:421-436 (schema)

  MCP tool schema definition including input schema, description, and parameters for 'get_requirements'.
  { name: "get_requirements", description: "Get all requirements or filter by type", inputSchema: { type: "object", properties: { project_path: { type: "string", description: "Path to manuscript directory (defaults to current directory)" }, requirement_type: { type: "string", enum: ["word_count", "citation_style", "formatting", "deadline", "target_audience", "tone", "reading_level", "chapter_count", "other"], description: "Filter by requirement type", }, enforced_only: { type: "boolean", description: "Show only enforced requirements" }, }, }, },
• src/index.ts:73-75 (registration)

  Registers the tool list handler which provides the 'get_requirements' schema to MCP clients.
  server.setRequestHandler(ListToolsRequestSchema, async () => ({ tools: writerToolDefinitions, }));
• src/index.ts:86-91 (registration)

  Instantiates WriterToolHandlers and calls handleTool() for tool execution in the MCP CallToolRequestHandler.
  const writersAid = new WritersAid({ projectPath }); const handlers = new WriterToolHandlers(writersAid); // Call the tool const result = await handlers.handleTool(name, args || {});
• src/memory/RequirementsManager.ts:174-185 (helper)

  Core database query helper that retrieves requirements by type from the SQLite database.
  getRequirementsByType(requirementType: RequirementType): WritingRequirement[] { const rows = this.db .prepare( `SELECT id, requirement_type, description, value, enforced, created_at FROM writing_requirements WHERE requirement_type = ? ORDER BY created_at DESC` ) .all(requirementType) as RequirementRow[]; return rows.map((row) => this.rowToRequirement(row)); }
