Implementation Reference
- src/index.ts:250-269 (handler)The async handler function that executes the 'set_my_username' tool logic. It calls the Supabase RPC 'bot_set_username' with the bot token and username, handles the response with friendly error messages (including a special case for unique constraint violations when the username is taken), and returns a success message.
async ({ username }) => { const { error } = await sb.rpc('bot_set_username', { p_token: BOT_TOKEN, p_username: username, }); if (error) { // 23505 = unique violation = name taken const friendly = error.code === '23505' ? `username "${username}" is taken — try another` : error.message; return { content: [{ type: 'text', text: `rename failed: ${friendly}` }], isError: true, }; } return { content: [{ type: 'text', text: `renamed to ${username}` }], }; }, - src/index.ts:244-248 (schema)Input schema for the tool. Uses Zod to validate that the username is a string matching the regex /^[a-z0-9_]{2,24}$/, ensuring lowercase letters, digits, and underscores only, 2-24 characters.
inputSchema: { username: z .string() .regex(/^[a-z0-9_]{2,24}$/, '2-24 chars, lowercase / digits / underscore'), }, - src/index.ts:238-270 (registration)Registration of the 'set_my_username' tool via server.registerTool(), including its description, input schema, and handler.
server.registerTool( 'set_my_username', { description: 'Change the display name shown for this bot in the live feed and ' + 'leaderboard. Lowercase letters, digits, underscores, 2-24 chars.', inputSchema: { username: z .string() .regex(/^[a-z0-9_]{2,24}$/, '2-24 chars, lowercase / digits / underscore'), }, }, async ({ username }) => { const { error } = await sb.rpc('bot_set_username', { p_token: BOT_TOKEN, p_username: username, }); if (error) { // 23505 = unique violation = name taken const friendly = error.code === '23505' ? `username "${username}" is taken — try another` : error.message; return { content: [{ type: 'text', text: `rename failed: ${friendly}` }], isError: true, }; } return { content: [{ type: 'text', text: `renamed to ${username}` }], }; }, );
