Implementation Reference

• src/tools/linear/get-profile.ts:83-136 (handler)

  The main handler function for the get_profile tool. It fetches the current user's profile from Linear using linearClient.viewer, processes it into a UserProfile object, formats it into human-readable text, and returns it as MCP content. Includes error handling.

  handler: async () => {
    try {
      // Get user profile data
      const profile = await linearClient.viewer;
      
      if (!profile) {
        return {
          content: [{
            type: "text",
            text: "Unable to retrieve user profile. Please check your connection to Linear.",
          }],
        };
      }
      
      // Convert to UserProfile format for safe processing
      const userProfile: UserProfile = {
        id: profile.id || "unknown-id",
        name: profile.name || "No Name",
        displayName: profile.displayName,
        email: profile.email,
        active: profile.active,
        admin: profile.admin,
        guest: profile.guest,
        createdAt: profile.createdAt,
        updatedAt: profile.updatedAt,
        lastSeen: profile.lastSeen,
        timezone: profile.timezone,
        createdIssueCount: profile.createdIssueCount,
        avatarBackgroundColor: profile.avatarBackgroundColor,
        url: profile.url,
        isMe: profile.isMe
      };
      
      // Format profile to human-readable text
      const formattedText = formatProfileToHumanReadable(userProfile);
      
      // Return formatted text
      return {
        content: [{
          type: "text",
          text: formattedText,
        }],
      };
    } catch (error) {
      // Handle errors gracefully
      const errorMessage = error instanceof Error ? error.message : "Unknown error";
      return {
        content: [{
          type: "text",
          text: `An error occurred while retrieving profile data:\n${errorMessage}`,
        }],
      };
    }
  }

• src/tools/linear/get-profile.ts:9-25 (schema)

  TypeScript interface defining the structure of the user profile data used within the tool handler.

  interface UserProfile {
    id: string;
    name: string;
    displayName?: string;
    email?: string;
    active?: boolean;
    admin?: boolean;
    guest?: boolean;
    createdAt?: string | Date;
    updatedAt?: string | Date;
    lastSeen?: string | Date;
    timezone?: string;
    createdIssueCount?: number;
    avatarBackgroundColor?: string;
    url?: string;
    isMe?: boolean;
  }

• src/index.ts:31-41 (registration)

  The get_profile tool (LinearGetProfileTool) is registered to the MCP server using registerTool, alongside other Linear tools.

  registerTool(server, [
    LinearSearchIssuesTool,
    LinearGetProfileTool,
    LinearCreateIssueTool,
    LinearCreateCommentTool,
    LinearUpdateCommentTool,
    LinearGetIssueTool,
    LinearGetTeamIdTool,
    LinearUpdateIssueTool,
    LinearGetCommentTool,
  ]);

• src/tools/linear/get-profile.ts:32-73 (helper)

  Helper function that converts UserProfile data into a formatted, human-readable multi-line string.

  function formatProfileToHumanReadable(profile: UserProfile): string {
    if (!profile || !profile.id) {
      return "Invalid or incomplete profile data";
    }
  
    let result = `User ID: ${profile.id}\n`;
    result += `Name: ${safeText(profile.name)}\n`;
    
    if (profile.displayName) {
      result += `Display name: ${safeText(profile.displayName)}\n`;
    }
    
    if (profile.email) {
      result += `Email: ${safeText(profile.email)}\n`;
    }
    
    result += `Status: ${profile.active ? "Active" : "Inactive"}\n`;
    result += `Admin: ${profile.admin ? "Yes" : "No"}\n`;
    result += `Guest: ${profile.guest ? "Yes" : "No"}\n`;
    
    if (profile.createdAt) {
      result += `Created at: ${formatDate(profile.createdAt)}\n`;
    }
    
    if (profile.lastSeen) {
      result += `Last seen: ${formatDate(profile.lastSeen)}\n`;
    }
    
    if (profile.timezone) {
      result += `Timezone: ${safeText(profile.timezone)}\n`;
    }
    
    if (profile.createdIssueCount !== undefined) {
      result += `Issues created: ${profile.createdIssueCount}\n`;
    }
    
    if (profile.url) {
      result += `URL: ${safeText(profile.url)}\n`;
    }
    
    return result;
  }
