Implementation Reference
- index.js:460-473 (registration)Registration of the 'get_token_summary' tool in the ListTools response, defining its name, description, and input schema (requires 'token_address').{ name: 'get_token_summary', description: 'Get AI-generated summary for a specific token', inputSchema: { type: 'object', properties: { token_address: { type: 'string', description: 'The token address hash to get summary for', }, }, required: ['token_address'], }, },
- index.js:747-748 (handler)The handler logic for executing the 'get_token_summary' tool: calls makeRequest to proxy the arguments to the ChainFETCH API endpoint '/api/v1/ethereum/tokens/summary'.case 'get_token_summary': return await this.makeRequest('/api/v1/ethereum/tokens/summary', 'GET', args, null, token);
- index.js:634-682 (helper)Shared helper method 'makeRequest' that performs authenticated HTTP requests to the ChainFETCH API, used by the get_token_summary handler and all other tools.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(); }
