Implementation Reference
- src/index.ts:721-726 (handler)The async handler function for the 'delete_thread' tool. It invokes the shared 'handleTool' helper to authenticate and call the Gmail API's users.threads.delete method with the provided thread ID.
async (params) => { return handleTool(config, async (gmail: gmail_v1.Gmail) => { const { data } = await gmail.users.threads.delete({ userId: 'me', id: params.id }) return formatResponse(data) }) } - src/index.ts:718-720 (schema)The input schema (Zod) for the 'delete_thread' tool, defining the required 'id' parameter as a string.
{ id: z.string().describe("The ID of the thread to delete") }, - src/index.ts:716-727 (registration)The registration of the 'delete_thread' tool using McpServer.tool(), including description, schema, and inline handler function.
server.tool("delete_thread", "Delete a thread", { id: z.string().describe("The ID of the thread to delete") }, async (params) => { return handleTool(config, async (gmail: gmail_v1.Gmail) => { const { data } = await gmail.users.threads.delete({ userId: 'me', id: params.id }) return formatResponse(data) }) } ) - src/index.ts:50-80 (helper)Shared 'handleTool' helper function used by 'delete_thread' (and all other tools) to handle OAuth2 authentication, credential validation, Gmail client creation, and error handling specific to auth failures.
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) { // Check for specific authentication errors if ( error.message?.includes("invalid_grant") || error.message?.includes("refresh_token") || error.message?.includes("invalid_client") || error.message?.includes("unauthorized_client") || error.code === 401 || error.code === 403 ) { return formatResponse({ error: `Authentication failed: ${error.message}. Please re-authenticate by running: npx @shinzolabs/gmail-mcp auth`, }); } return formatResponse({ error: `Tool execution failed: ${error.message}` }); } } - src/index.ts:48-48 (helper)Utility 'formatResponse' function used by 'delete_thread' (and all tools) to standardize tool responses in MCP format.
const formatResponse = (response: any) => ({ content: [{ type: "text", text: JSON.stringify(response) }] })
