MCP Server - Implement error handling

[linear]

Right know, error handling is done manually by users, like so:

function handleError(err: unknown) {
  const eventId = Sentry.captureException(error);

  return [
    "**Error**",
    "There was an problem with your request.",
    "Please report the following to the user:",
    `**Event ID**: ${eventId}`,
    process.env.NODE_ENV !== "production"
      ? error instanceof Error
        ? error.message
        : String(error)
      : "",
  ].join("\n\n");
}
