Implementation Reference
- src/tools/toolFactory.ts:21-76 (handler)Generic handler function for all API-based tools, including get-ticker-exchanges. Determines if local or API call, then invokes universalApiHandler with the tool's endpoint '/tickers/exchanges', GET method, and basePath from constants.
server.tool(config.name, config.description, config.parameters, async (params: Record<string, any>) => { // Handle local operations if (config.isLocal) { // Handle specific local tools if (config.name === 'save-share-token') { await saveToCache('shareToken', params.shareToken); return { content: [ { type: 'text', text: 'Share token saved successfully', }, ], }; } if (config.name === 'get-share-token') { const shareToken = await getFromCache('shareToken'); return { content: [ { type: 'text', text: shareToken ? shareToken : 'No share token found in cache', isError: !shareToken, }, ], }; } // Future local tools can be added here // Default response for unhandled local tools return { content: [ { type: 'text', text: 'Operation completed', }, ], }; } // Handle API operations const basePath = config.basePath || COINSTATS_API_BASE; const method = config.method || 'GET'; // Methods that typically have a request body const bodyMethods = ['POST', 'PUT', 'PATCH', 'DELETE']; // For GET/DELETE requests, all params go in the URL // For POST/PUT/PATCH, send params as the body if (bodyMethods.includes(method.toUpperCase())) { return universalApiHandler(basePath, config.endpoint, method, {}, params); } else { return universalApiHandler(basePath, config.endpoint, method, params); } - src/tools/toolConfigs.ts:130-136 (schema)Schema definition for the get-ticker-exchanges tool, including name, description, endpoint, method, and empty parameters schema.
{ name: 'get-ticker-exchanges', description: 'Get a list of supported exchanges.', endpoint: '/tickers/exchanges', method: 'GET', parameters: {}, }, - src/index.ts:18-18 (registration)Registers all tools, including get-ticker-exchanges, by calling registerTools with the MCP server instance and allToolConfigs.
registerTools(server, allToolConfigs); - src/tools/toolFactory.ts:19-79 (registration)Registers each tool configuration with the MCP server by calling server.tool for every config in allToolConfigs.
