Implementation Reference
- src/tools/thread-tools.ts:280-300 (handler)Executes the join_thread tool: fetches Discord guild and thread by ID, validates it's a thread, calls thread.join() to make bot join, handles errors, and returns JSON response.async ({ guildId, threadId }) => { const result = await withErrorHandling(async () => { const client = await getDiscordClient(); const guild = await client.guilds.fetch(guildId); const thread = await guild.channels.fetch(threadId); if (!thread || !thread.isThread()) { throw new Error('Thread not found'); } await thread.join(); return { threadId, threadName: thread.name, message: 'Joined thread successfully' }; }); if (!result.success) { return { content: [{ type: 'text', text: result.error }], isError: true }; } return { content: [{ type: 'text', text: JSON.stringify(result.data, null, 2) }] }; }
- src/tools/thread-tools.ts:276-279 (schema)Input schema using Zod validators for required parameters guildId and threadId.{ guildId: z.string().describe('The ID of the server (guild)'), threadId: z.string().describe('The ID of the thread'), },
- src/tools/thread-tools.ts:274-301 (registration)Registers the 'join_thread' tool with MCP server using server.tool(name, description, inputSchema, handlerFn).'join_thread', 'Make the bot join a thread', { guildId: z.string().describe('The ID of the server (guild)'), threadId: z.string().describe('The ID of the thread'), }, async ({ guildId, threadId }) => { const result = await withErrorHandling(async () => { const client = await getDiscordClient(); const guild = await client.guilds.fetch(guildId); const thread = await guild.channels.fetch(threadId); if (!thread || !thread.isThread()) { throw new Error('Thread not found'); } await thread.join(); return { threadId, threadName: thread.name, message: 'Joined thread successfully' }; }); if (!result.success) { return { content: [{ type: 'text', text: result.error }], isError: true }; } return { content: [{ type: 'text', text: JSON.stringify(result.data, null, 2) }] }; } );
- src/index.ts:63-63 (registration)Top-level invocation of registerThreadTools which includes the join_thread tool registration.registerThreadTools(server);
