It fetches user data from Reddit using the client, formats it with formatUserInfo, and returns a formatted MCP response.export async function getUserInfo(params: { username: string }) { const { username } = params; const client = getRedditClient(); if (!client) { throw new McpError( ErrorCode.InternalError, "Reddit client not initialized" ); } try { console.log(`[Tool] Getting info for u/${username}`); const user = await client.getUser(username); const formattedUser = formatUserInfo(user); return { content: [ { type: "text", text: ` # User Information: u/${formattedUser.username} ## Profile Overview - Username: u/${formattedUser.username} - Karma: - Comment Karma: ${formattedUser.karma.commentKarma.toLocaleString()} - Post Karma: ${formattedUser.karma.postKarma.toLocaleString()} - Total Karma: ${formattedUser.karma.totalKarma.toLocaleString()} - Account Status: ${formattedUser.accountStatus.join(", ")} - Account Created: ${formattedUser.accountCreated} - Profile URL: ${formattedUser.profileUrl} ## Activity Analysis - ${formattedUser.activityAnalysis.replace(/\n - /g, "\n- ")} ## Recommendations - ${formattedUser.recommendations.replace(/\n - /g, "\n- ")} `, }, ], }; } catch (error) { console.error(`[Error] Error getting user info: ${error}`); throw new McpError( ErrorCode.InternalError, `Failed to fetch user data: ${error}` ); } }
