Implementation Reference
- src/index.ts:763-769 (handler)The handler function for the 'modify_thread' tool. It destructures the thread ID and passes the remaining params as threadData to the Gmail API's threads.modify method via the shared handleTool utility.
async (params) => { const { id, ...threadData } = params return handleTool(config, async (gmail: gmail_v1.Gmail) => { const { data } = await gmail.users.threads.modify({ userId: 'me', id, requestBody: threadData }) return formatResponse(data) }) } - src/index.ts:759-762 (schema)Zod input schema defining parameters for the 'modify_thread' tool: required thread ID and optional label IDs to add or remove.
id: z.string().describe("The ID of the thread to modify"), addLabelIds: z.array(z.string()).optional().describe("A list of label IDs to add to the thread"), removeLabelIds: z.array(z.string()).optional().describe("A list of label IDs to remove from the thread") }, - src/index.ts:756-770 (registration)Registration of the 'modify_thread' tool using server.tool(), including description, input schema, and inline handler function.
server.tool("modify_thread", "Modify the labels applied to a thread", { id: z.string().describe("The ID of the thread to modify"), addLabelIds: z.array(z.string()).optional().describe("A list of label IDs to add to the thread"), removeLabelIds: z.array(z.string()).optional().describe("A list of label IDs to remove from the thread") }, async (params) => { const { id, ...threadData } = params return handleTool(config, async (gmail: gmail_v1.Gmail) => { const { data } = await gmail.users.threads.modify({ userId: 'me', id, requestBody: threadData }) return formatResponse(data) }) } ) - src/index.ts:49-65 (helper)Shared 'handleTool' utility function used by the 'modify_thread' handler to manage OAuth2 authentication, Gmail client creation, and API call execution with 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}` } } - src/index.ts:47-47 (helper)Utility function 'formatResponse' used by the 'modify_thread' handler to format the API response as MCP content.
const formatResponse = (response: any) => ({ content: [{ type: "text", text: JSON.stringify(response) }] })
