Implementation Reference
- index.js:240-253 (registration)Registration of the 'get_transaction_summary' tool in the ListToolsRequestSchema handler, including its description and input schema definition.{ name: 'get_transaction_summary', description: 'Get AI-generated summary for a specific transaction', inputSchema: { type: 'object', properties: { transaction_hash: { type: 'string', description: 'The transaction hash to get summary for', }, }, required: ['transaction_hash'], }, },
- index.js:713-714 (handler)Handler implementation for the get_transaction_summary tool within the handleToolCall switch statement. It forwards the request to the ChainFETCH API endpoint for transaction summaries.case 'get_transaction_summary': return await this.makeRequest('/api/v1/ethereum/transactions/summary', 'GET', args, null, token);
- index.js:634-682 (helper)Helper method 'makeRequest' used by the tool handler to make authenticated HTTP requests to the ChainFETCH API base URL.async makeRequest(endpoint, method = 'GET', params = {}, body = null, token = null) { const chainfetchToken = token || process.env.CHAINFETCH_API_TOKEN; if (!chainfetchToken) { throw new McpError( ErrorCode.InvalidRequest, 'CHAINFETCH_API_TOKEN is required' ); } const url = new URL(`${API_BASE_URL}${endpoint}`); // Add query parameters for GET requests if (method === 'GET' && Object.keys(params).length > 0) { Object.entries(params).forEach(([key, value]) => { if (value !== undefined && value !== null) { if (Array.isArray(value)) { value.forEach(v => url.searchParams.append(`${key}[]`, v)); } else { url.searchParams.append(key, value.toString()); } } }); } const fetchOptions = { method, headers: { 'Authorization': `Bearer ${chainfetchToken}`, 'Content-Type': 'application/json', }, }; if (body && method !== 'GET') { fetchOptions.body = JSON.stringify(body); } const response = await fetch(url.toString(), fetchOptions); if (!response.ok) { const errorText = await response.text(); throw new McpError( ErrorCode.InternalError, `API request failed: ${response.status} ${response.statusText} - ${errorText}` ); } return await response.json(); }
