minecraft_wiki
Search and retrieve detailed information from the official Minecraft Wiki for Bedrock and Education Editions. Focus on commands, blocks, items, entities, and mechanics using a step-by-step sequence for efficient information gathering.
Instructions
Search Minecraft Wiki for Bedrock Edition and Education Edition commands, blocks, items, entities, and game mechanics. Excludes Java Edition-only features. Returns accurate, up-to-date information from the official Minecraft Wiki. Use sequence action for step-by-step information gathering: 1) search for topic, 2) get specific page, 3) get detailed section - reduces overwhelming responses.
Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| action | Yes | Wiki search action to perform | |
| focus | No | Focus area for search results | |
| page_title | No | Specific wiki page title to retrieve | |
| query | No | Search query (e.g., "give command", "diamond sword", "teleport", "setblock") | |
| section | No | Specific section name within a page | |
| steps | No | Array of wiki search actions for sequence. Example: [{"type":"search","query":"give command","focus":"commands"},{"type":"get_page","title":"Commands/give"},{"type":"get_section","title":"Commands/give","section":"Syntax"}]. Use this to break down information gathering into manageable steps instead of getting overwhelming responses. | |
| title | No | Wiki page title (alternative parameter name for compatibility) |
Implementation Reference
- src/tools/core/minecraft-wiki.ts:84-159 (handler)The primary handler method that processes input arguments, dispatches to specific wiki operations based on the 'action' parameter (search, get_page, get_section, sequence), calls helper methods, and returns structured ToolCallResult.
async execute(args: { action: string; query?: string; page_title?: string; title?: string; section?: string; focus?: string; steps?: SequenceStep[]; }): Promise<ToolCallResult> { try { const { action } = args; let result: any; let message: string; switch (action) { case 'search': if (!args.query) { return { success: false, message: 'Query required for search action' }; } result = await this.searchWiki(args.query, args.focus); message = `Wiki search completed for: "${args.query}"`; break; case 'get_page': const pageTitle = args.page_title || args.title; if (!pageTitle) { return { success: false, message: 'Page title required for get_page action' }; } result = await this.getPageContent(pageTitle); message = `Retrieved wiki page: "${pageTitle}"`; break; case 'get_page_summary': const summaryTitle = args.page_title || args.title; if (!summaryTitle) { return { success: false, message: 'Page title required for get_page_summary action' }; } result = await this.getPageSummary(summaryTitle); message = `Retrieved wiki page summary: "${summaryTitle}"`; break; case 'get_section': const sectionPageTitle = args.page_title || args.title; if (!sectionPageTitle || !args.section) { return { success: false, message: 'Page title and section required for get_section action' }; } result = await this.getPageSection(sectionPageTitle, args.section); message = `Retrieved section "${args.section}" from page "${sectionPageTitle}"`; break; case 'sequence': if (!args.steps) { return this.createErrorResponse('steps array is required for sequence action'); } return await this.executeSequence(args.steps as SequenceStep[]); default: return { success: false, message: `Unknown action: ${action}. Supported actions: search, get_page, get_page_summary, get_section, sequence` }; } return { success: true, message: message, data: { action, result, timestamp: Date.now() } }; } catch (error) { return { success: false, message: `Minecraft Wiki search error: ${error instanceof Error ? error.message : String(error)}` }; } } - Defines the input schema with required 'action' and optional parameters for querying the Minecraft Wiki, including support for sequence steps.
