Cursor Conversations MCP Server

Instructions

Implementation Reference

• src/tools/conversation-tools.ts:56-159 (handler)

  Primary handler function implementing the core logic for listing Cursor conversations. Validates input, connects to Cursor database, applies filters (projectPath, keywords, dates, etc.), retrieves matching conversation IDs, generates summaries with AI summaries/titles, and returns paginated results with metadata.
  export async function listConversations(input: ListConversationsInput): Promise<ListConversationsOutput> { const validatedInput = listConversationsSchema.parse(input); const dbPath = process.env.CURSOR_DB_PATH || detectCursorDatabasePath(); const reader = new CursorDatabaseReader({ dbPath }); try { await reader.connect(); const filters: ConversationFilters = { minLength: validatedInput.minLength, format: validatedInput.format, hasCodeBlocks: validatedInput.hasCodeBlocks, keywords: validatedInput.keywords, projectPath: validatedInput.projectPath, filePattern: validatedInput.filePattern, relevantFiles: validatedInput.relevantFiles }; // Add date range filter if provided if (validatedInput.startDate || validatedInput.endDate) { const start = validatedInput.startDate ? new Date(validatedInput.startDate) : new Date('1970-01-01'); const end = validatedInput.endDate ? new Date(validatedInput.endDate) : new Date(); filters.dateRange = { start, end }; } const conversationIds = await reader.getConversationIds(filters); let limitedIds = conversationIds.slice(0, validatedInput.limit); // Apply date filtering if specified (post-query filtering due to unreliable timestamps) if (validatedInput.startDate || validatedInput.endDate) { const filteredIds = []; for (const composerId of limitedIds) { try { const conversation = await reader.getConversationById(composerId); if (!conversation) continue; const hasValidDate = checkConversationDateRange( conversation, validatedInput.startDate, validatedInput.endDate ); if (hasValidDate) { filteredIds.push(composerId); } } catch (error) { // Skip conversations that can't be processed continue; } } limitedIds = filteredIds; } const conversations = []; for (const composerId of limitedIds) { try { const summary = await reader.getConversationSummary(composerId, { includeFirstMessage: true, maxFirstMessageLength: 150, includeTitle: true, includeAIGeneratedSummary: validatedInput.includeAiSummaries }); if (summary) { conversations.push({ composerId: summary.composerId, format: summary.format, messageCount: summary.messageCount, hasCodeBlocks: summary.hasCodeBlocks, relevantFiles: summary.relevantFiles || [], attachedFolders: summary.attachedFolders || [], firstMessage: summary.firstMessage, title: summary.title, aiGeneratedSummary: summary.aiGeneratedSummary, size: summary.conversationSize }); } } catch (error) { console.error(`Failed to get summary for conversation ${composerId}:`, error); } } return { conversations, totalFound: conversationIds.length, filters: { limit: validatedInput.limit ?? 10, minLength: validatedInput.minLength ?? 100, format: validatedInput.format ?? 'both', hasCodeBlocks: validatedInput.hasCodeBlocks, keywords: validatedInput.keywords, projectPath: validatedInput.projectPath, filePattern: validatedInput.filePattern, relevantFiles: validatedInput.relevantFiles, includeAiSummaries: validatedInput.includeAiSummaries } }; } finally { // Always close the database connection reader.close(); } }
• src/server.ts:51-140 (registration)

  MCP tool registration for 'list_conversations' including description, Zod input schema with parameters like projectPath, limit, dates, and async handler wrapper that calls the core listConversations function (or getConversationsByProject for project relevance scoring).

• src/tools/conversation-tools.ts:8-21 (schema)

  Internal Zod schema for validating inputs to the listConversations handler, defining parameters like limit, minLength, projectPath filtering, keywords, date ranges, and AI summary inclusion.
  export const listConversationsSchema = z.object({ limit: z.number().min(1).max(1000).optional(), minLength: z.number().min(0).optional(), keywords: z.array(z.string()).optional(), hasCodeBlocks: z.boolean().optional(), format: z.enum(['legacy', 'modern', 'both']).optional(), includeEmpty: z.boolean().optional(), projectPath: z.string().optional(), filePattern: z.string().optional(), relevantFiles: z.array(z.string()).optional(), startDate: z.string().optional(), endDate: z.string().optional(), includeAiSummaries: z.boolean().optional().default(true) });
• src/tools/conversation-tools.ts:1110-1184 (handler)

  Supporting handler getConversationsByProject used in the list_conversations wrapper for project-specific filtering with relevance scoring based on file/folder path matching.
