Implementation Reference

• src/index.ts:280-381 (handler)

  The MCP tool handler that processes input parameters, fetches items via API client, formats them into markdown with metadata, handles pagination and token limits, and returns structured content or error messages.
  async ({ listId, githubRepo, section, subcategory, tokens = DEFAULT_MINIMUM_TOKENS, offset = 0 }) => { if (!listId && !githubRepo) { return { content: [ { type: "text", text: "Either listId or githubRepo must be provided. Use 'find_awesome_section' first to discover available lists and sections.", }, ], }; } try { const response = await apiClient.getItems({ listId, githubRepo, section, subcategory, tokens, offset, }); if (!response.items || response.items.length === 0) { return { content: [ { type: "text", text: "No items found for the specified criteria. Try adjusting your filters or use find_awesome_section to discover available sections.", }, ], }; } const { metadata, items, tokenUsage } = response; const header = `# ${metadata.list.name}` + (metadata.section ? ` - ${metadata.section}` : '') + (metadata.subcategory ? ` > ${metadata.subcategory}` : '') + '\n\n'; const listDescription = metadata.list.description ? `> ${metadata.list.description}\n\n` : ''; const formattedItems = items .map((item, index) => { let itemText = `## ${index + 1}. ${item.name}\n\n`; if (item.description) { itemText += `${item.description}\n\n`; } itemText += `**URL**: ${item.url}\n`; if (item.githubRepo) { itemText += `**GitHub**: https://github.com/${item.githubRepo}\n`; } if (item.githubStars) { itemText += `**Stars**: ${item.githubStars.toLocaleString()}\n`; } if (item.tags && item.tags.length > 0) { itemText += `**Tags**: ${item.tags.join(', ')}\n`; } return itemText; }) .join('\n---\n\n'); const footer = `\n---\n\n` + `## Metadata\n\n` + `- **Token usage**: ${tokenUsage.used.toLocaleString()}/${tokenUsage.limit.toLocaleString()}` + (tokenUsage.truncated ? ' (truncated)' : '') + '\n' + `- **Items displayed**: ${items.length} of ${metadata.totalItems}\n` + (metadata.hasMore ? `- **Next page**: Use \`offset: ${metadata.offset + items.length}\` to get more items\n` : ''); return { content: [ { type: "text", text: header + listDescription + formattedItems + footer, }, ], }; } catch (error: any) { const apiError = error as APIError; return { content: [ { type: "text", text: apiError.message || "Failed to retrieve items. Please check your parameters and try again.", }, ], }; } }
• src/index.ts:248-278 (schema)

  Zod schema for input validation of the tool parameters including listId, githubRepo, section, subcategory, tokens (with preprocessing and transformation), and offset.
  inputSchema: { listId: z .string() .optional() .describe("UUID of the list (from find_awesome_section results)"), githubRepo: z .string() .optional() .describe("GitHub repo path (e.g., 'sindresorhus/awesome') from find_awesome_section results"), section: z .string() .optional() .describe("Category/section name to filter"), subcategory: z .string() .optional() .describe("Subcategory to filter"), tokens: z .preprocess((val) => (typeof val === "string" ?

DEFAULT_MINIMUM_TOKENS : val)) .optional() .describe( `Maximum number of tokens to return (default: ${DEFAULT_MINIMUM_TOKENS}). Higher values provide more items but consume more tokens.` ), offset: z .number() .min(0) .optional() .default(0) .describe("Pagination offset for retrieving more items"), },
• src/index.ts:241-382 (registration)

  Registration of the get_awesome_items tool with the MCP server, including name, title, description, input schema, and handler reference.

• src/api-client.ts:144-206 (helper)

  Helper method in API client that performs HTTP GET to /api/get-items, normalizes response data, estimates and enforces token limits by truncating items, and structures the output for the tool handler.
  async getItems(params: GetItemsParams): Promise<GetItemsResponse> { this.log('Getting items with params:', params); if (!params.listId && !params.githubRepo) { const error: APIError = { code: 'INVALID_PARAMS', message: 'Either listId or githubRepo must be provided', }; throw error; } const response = await this.request<any>('/api/get-items', { listId: params.listId, githubRepo: params.githubRepo, section: params.section, subcategory: params.subcategory, limit: params.tokens ? Math.floor(params.tokens / 50) : undefined, offset: params.offset, }); const items = response.items || response.data || []; const metadata = response.metadata || response.meta || {}; const tokenCount = this.estimateTokens(items); const tokenLimit = params.tokens || 10000; const truncated = tokenCount > tokenLimit; const truncatedItems = truncated ? this.truncateToTokenLimit(items, tokenLimit) : items; return { items: truncatedItems.map((item: any) => ({ id: item.id || item._id || '', name: item.name || item.title || '', description: item.description || '', url: item.url || item.link || '', githubStars: item.stars || item.githubStars || item.github_stars, githubRepo: item.repo || item.githubRepo || item.github_repo, tags: item.tags || [], lastUpdated: item.lastUpdated || item.updated_at || item.last_updated, })), metadata: { list: { id: metadata.listId || metadata.list_id || params.listId || '', name: metadata.listName || metadata.list_name || '', githubRepo: metadata.githubRepo || metadata.github_repo || params.githubRepo || '', description: metadata.description || '', totalItems: metadata.totalItems || metadata.total_items || items.length, }, section: metadata.section || params.section, subcategory: metadata.subcategory || params.subcategory, totalItems: metadata.totalItems || metadata.total_items || items.length, offset: metadata.offset || params.offset || 0, hasMore: metadata.hasMore || metadata.has_more || false, }, tokenUsage: { used: this.estimateTokens(truncatedItems), limit: tokenLimit, truncated, }, }; }
• src/types.ts:24-67 (schema)

  TypeScript interfaces defining input (GetItemsParams) and output (GetItemsResponse) structures used by the API client for type safety.
  export interface GetItemsParams { listId?: string; githubRepo?: string; section?: string; subcategory?: string; tokens?: number; offset?: number; } export interface AwesomeItem { id: string; name: string; description: string; url: string; githubStars?: number; githubRepo?: string; tags?: string[]; lastUpdated?: string; } export interface ListMetadata { id: string; name: string; githubRepo: string; description?: string; totalItems: number; } export interface GetItemsResponse { items: AwesomeItem[]; metadata: { list: ListMetadata; section?: string; subcategory?: string; totalItems: number; offset: number; hasMore: boolean; }; tokenUsage: { used: number; limit: number; truncated: boolean; }; }
