Implementation Reference
- src/index.ts:514-527 (registration)Registration of the 'batch_modify_messages' tool, including inline schema definition and handler function that invokes the Gmail API's batchModify method via the shared handleTool utility.server.tool("batch_modify_messages", "Modify the labels on multiple messages", { ids: z.array(z.string()).describe("The IDs of the messages to modify"), addLabelIds: z.array(z.string()).optional().describe("A list of label IDs to add to the messages"), removeLabelIds: z.array(z.string()).optional().describe("A list of label IDs to remove from the messages") }, async (params) => { return handleTool(config, async (gmail: gmail_v1.Gmail) => { const { data } = await gmail.users.messages.batchModify({ userId: 'me', requestBody: { ids: params.ids, addLabelIds: params.addLabelIds, removeLabelIds: params.removeLabelIds } }) return formatResponse(data) }) } )
- src/index.ts:521-526 (handler)Handler function that wraps the Gmail users.messages.batchModify API call using the shared handleTool, handling authentication and error management, and formats the response.async (params) => { return handleTool(config, async (gmail: gmail_v1.Gmail) => { const { data } = await gmail.users.messages.batchModify({ userId: 'me', requestBody: { ids: params.ids, addLabelIds: params.addLabelIds, removeLabelIds: params.removeLabelIds } }) return formatResponse(data) }) }
- src/index.ts:516-520 (schema)Zod schema defining input parameters: required 'ids' array of message IDs, optional 'addLabelIds' and 'removeLabelIds' arrays for label modifications.{ ids: z.array(z.string()).describe("The IDs of the messages to modify"), addLabelIds: z.array(z.string()).optional().describe("A list of label IDs to add to the messages"), removeLabelIds: z.array(z.string()).optional().describe("A list of label IDs to remove from the messages") },
- src/index.ts:49-65 (helper)Shared helper function 'handleTool' used by all tools, including batch_modify_messages, to manage OAuth2 authentication, Gmail client creation, API execution, and error handling.const handleTool = async (queryConfig: Record<string, any> | undefined, apiCall: (gmail: gmail_v1.Gmail) => Promise<any>) => { try { const oauth2Client = queryConfig ? createOAuth2Client(queryConfig) : defaultOAuth2Client if (!oauth2Client) throw new Error('OAuth2 client could not be created, please check your credentials') const credentialsAreValid = await validateCredentials(oauth2Client) if (!credentialsAreValid) throw new Error('OAuth2 credentials are invalid, please re-authenticate') const gmailClient = queryConfig ? google.gmail({ version: 'v1', auth: oauth2Client }) : defaultGmailClient if (!gmailClient) throw new Error('Gmail client could not be created, please check your credentials') const result = await apiCall(gmailClient) return result } catch (error: any) { return `Tool execution failed: ${error.message}` } }
